. . . Four Distinct Societies Present Unified Program at MS&T '05

Materials Science and Technology 2005 (MS&T '05) spoke to a concern frequently voiced by materials society members: a need for fewer competing conferences and more collaboration. The meeting combined the resources of the American Ceramic Society (ACerS), ASM International, the Association for Iron and Steel Technology (AIST), and TMS and was held in conjunction with ASM's Heat Treating Conference and Exposition. Prior to the final plenary presentation of MS&T, Ron Ashburn, executive director of AIST, offered these preliminary numbers from the event as a whole:

  • 4,700 registrants
  • 970 technical presentations
  • 336 exhibiting companies
  • 39 technical symposia
All full-conference registrants of MS&T received a copy of the complete published proceedings from the meeting on CD-ROM. In addition, three hard-cover proceedings volumes from the conference were published and are now available for purchase through the TMS Document Center. (Highlights from some of these books can be found in the Editors' Choice column.) By year's end, all of the available papers from MS&T '05 will be accessible via a new web site that will serve as a central repository for all MS&T meeting publications. From this site, visitors will be able to purchase individual papers, whole proceedings, or construct custom collections.

ALL-CONFERENCE PLENARY PRESENTATIONS FOCUS ON DIVERSE TECHNOLOGIES . . . [TOP]
NEWS

. . . With Informatics, Regenerative Biomaterials, and Technology Management in the Spotlight

A unique aspect of MS&T '05 was the tactic of opening each programming day with a one-hour conference-wide plenary session. The plenaries attracted large numbers of conference goers to an eclectic mix of presentations that generally reflected the overall diversity of the MS&T technical program.

From an organizational perspective, the fastest pace plenary session came first: Moving Materials Informatics Forward. Its 60 minutes featured not only opening comments from the moderator (Toni Marechaux) but three brief presentations and a panel discussion on the challenges that this interactive and iterative process presents to the materials community. Noting that collaboration is a win for everyone, the panel emphasized the need for integrating model development with the need for knowledge (not simple data) extraction. All underscored the need to be mindful of product design objectives and opportunities and to learn from the biotechnology community, which successfully applied similar tactics in the Human Genome Project. Approximately 50 people attended.

The next day's plenary talk, from the very same biotechnology community, attracted an audience of twice the size to hear Alan J. Russell of the Pittsburgh Tissue Engineering Initiative discuss materials opportunities in tissue regeneration. Materials, he said, are but one of three resources in the biotechnologist's toolbox, along with cell therapies and artificial devices. Emphasizing greater collaboration among the bio and materials communities, he described a goal of seamlessly meshing tissue with a nondegradeable material. With nanotechnology enabling the emulation of nature's molecular-level complexities, the time may be right to achieve such interfaces and thereby regenerate damaged areas of the body rather than just treating the symptoms.

The final plenary presentation was delivered by Markos Tambakeras, the chair, president, and chief executive officer of Kennametal (pictured). A "long ago scientist who became a business man," Tambakeras described how Kennametal uses science in its products to provide a competitive edge for customers. To achieve this mission, approximately 1,000 of the company's 14,000 employees are engineers. He attributed two thirds of the company's growth directly to the application of technology. As such, he spent a portion of his talk warning of diminishing numbers in the U.S. engineering workforce and providing recommendations to educators (stress math and science), industry (emphasize diversity), government (promote R&D), and individuals (be a mentor). About 140 people attended.

TMS ROLLS OUT VOLUNTEER RESOURCES [TOP]
NEWS
ITEM

Information Session at MS&T Will be Complemented by New Web Sites

Making the work of TMS volunteers more efficient and effective is important to member satisfaction. At MS&T '05, two new initiatives were highlighted in this area. The first is the revamping of the on-line resources available to assist TMS volunteers through the Administration@TMS area on the TMS web site. Now undergoing final revisions with a planned public launch in late October, Administration@TMS will be the volunteer's "one-stop" resource for information on TMS Technical Divisions as well as technical and administrative committees. Especially exciting are the new Committee Home Pages, which will contain valuable information on the programming, publication, and other activities of the Technical Committees that is accessible to members and the public alike. Administration@TMS will also contain a "how to" question-and-answer section along with TMS policies and procedures that will make finding the right answer to those daunting volunteer questions much easier.

Also initiated at MS&T '05 was a Technical Division and Committee Information Session, in which TMS staff provided volunteer leaders with a briefing of new TMS initiatives as well as key support services that are available to them. Attendees at this session uniformly found it of high value (and also liked the free lunch!). Another session will be held at the 2006 TMS Annual Meeting for committee and council members, symposium organizers, and others who seek to be TMS volunteer leaders.

. . . Comments Overheard at MS&T '05

The following comments from the sessions and hallways of MS&T '05 are a sampling of the exchanges that take place when materials scientists and engineers gather. What follows are ten of our favorites. We couldn't contain ourselves on this one, so for additional comments from MS&T '05, see "Parting Words" near the end of this special edition of TMS e-News.

10. "We are running behind, but time shouldn't come in the way of scholarly exchange."

9. "The Diamond Age by Neal Stephenson is the best materials book, ever."

8. "When we speak of nuclear power, everybody, at least Jane Fonda, backs away. And she's one of the leaders of the technical world."

7. "The very thing we don't know how to do well is the very thing we're avoiding: the production of hydrogen."

6. "War's a wonderful thing for advancing technology; it's bad for other things."

5. "It's a shame the technical sessions are so popular. It really hurt the attendance at the exhibit."

4. "It's a shame the exhibit is so big. It really hurt the attendance at technical sessions."

3. "At MS&T, you're exposed to more professionals in the materials community than anywhere else in the world."

2. "There are too many challenges for any company or group of companies to overcome. We need active partnerships."

1. "I'm not a materials scientist, but I can fake it OK."

ATTENDEES LOOK AT TECHNOLOGY OF THE PAST . . . [TOP]

ITEM

. . . During History and Archaeology of Materials Sessions

While discussions down the hall focused on such forward-looking topics as nanomaterials characterization and next-generation biomaterials, in Room 402 of the David L. Lawrence Convention Center the view was toward the past. In the History and Archaeology of Materials sessions on September 27, MS&T '05 attendees learned about such topics as the advanced workmanship that went into early Damascus steel and pre-Hispanic Au-Pt sintering for alloy manufacture.

The unique symposium was organized by TMS Past President Greg Hildeman of Alcoa and Michael R. Notis and Aaron Shugar, both of Lehigh University. It included nine papers, two of which had Pittsburgh themes. One session focused on John Roebling, who designed the first wire-rope suspension bridge. Roebling once lived in a Pittsburgh suburb and designed two bridges in the city before he designed the Brooklyn Bridge. Another session offered an analysis of the steel used in Fallingwater, architect Frank Lloyd Wright's signature home built about 80 miles from Pittsburgh.

Attendance ranged from 40 to 65 at the morning sessions, tapering to about 20 by the end of the day.

Stefanie Price, a materials engineering senior at the University of Alberta, said she particularly enjoyed two presentations: The Sacred in MesoAmerican Materials and Crucible Damascus Steel: Origins and Influence. "What really caught my attention was the fact that neither talk focused solely on the technical side of materials engineering but rather on how the materials initially fit into the daily lives of the people who first discovered them," she said.

Those who missed this study in archaeotechnology will have an opportunity to review some of the presentations in print. Several of the papers are planned for publication in the May 2006 issue of JOM.

NIST BREAKS DOWN BARRIERS TO INNOVATION . . . [TOP]
NEWS
ITEM

. . . With Development of Standardized U.S. Measurement System

Innovation is key to the success of any nation's economy. To help remove potential barriers to innovation in the United States, the U.S. National Institute of Standards and Technology (NIST) plans to develop a standardized system of measurement solutions that could save U.S. industries both time and money. A workshop held at MS&T '05 introduced attendees to the program and sought specific input for measurement standard needs.

"If you can't measure what you need to measure, you can't innovate," said presenter David Hermreck of NIST.

Companies often work individually to develop metrology solutions for a single project, Hermreck said, but public access to established metrology standards could save companies time and money. The goal of the U.S. Measurement System Project is to develop a roadmap that identifies U.S. priority measurement needs and to eventually offer standardized solutions.

The multi-year effort is now in its earliest stages, where NIST is seeking to identify high-priority measurement needs from various industrial sectors. In this stage of the project, NIST is seeking input from the industrial community through workshops and other collaborative events. For more information on how your company can provide input on measurement needs, write to usms@nist.gov.

HOW TO . . . [TOP]
NEWS
ITEM

. . . Take on a Leadership Role at TMS

Taking on a position of leadership in a professional society is a daunting task. Leadership roles vary and can include serving as a symposium organizer, a session or committee chair, or a publications editor. A panel of leaders from TMS, AIST, and ACerS helped to demystify the process of getting started at the MS&T '05 Young Leaders Tutorial Luncheon.

Over a boxed lunch, society representatives Dan Thoma of TMS, Katherine Faber of ACerS, and Mark Blankenau of AIST shared stories of how they moved up the ranks in their respective societies and offered young members advice on how to do the same. Before taking on any leadership role in a society, panelists advised attendees to first consult with their employers to determine if adequate time and resources would be available.

Once support is secured, there are a number of ways to become involved in society activities. For example, someone interested in programming could select a symposium in their area of expertise from the MS&T '06 Call for Papers, contact the symposium organizer, and offer to serve as a session chair. Another option for beginners is to attend a technical committee meeting related to their interests and to offer to help with a committee project. For professionals under the age of 35, the TMS Young Leader Intern program is an effective way to learn the behind-the-scenes workings of the society. (Applications for the 2006 program will be accepted through October 18, 2005.) Yet another way to begin participation is to contact a member of the TMS staff, who can connect volunteers with the appropriate people and activities.

Societies, symposium organizers, and committees are always in need of volunteers and offers of help are not likely to be turned down, the panelists assured their audience.

. . . At MS&T Undergraduate Student Speaking Contest

When Kendra Erk gave her technical talk on thermal barrier coatings, she stood confidently in front of the room, wielding her laser pointer like a pro. At least that was the view from the audience's seats. Erk's perspective, however, was quite different.

"My hand was shaking, my voice was shaking, but apparently no one notices but yourself,” she said.

Erk, a materials science student from Purdue University, managed to overcome her jitters and win second place in the Undergraduate Student Speaking Contest, a new event for the MS&T conference. The contest is intended to sharpen the communication skills of students, said William Fahrenholtz, assistant professor in the ceramic engineering department of the University of Missouri-Rolla and organizer of the event. Fahrenholtz said undergraduate student speaking contests have been popular at ACerS conferences for years. This year, with the entry of ACerS as a partner in MS&T, the learning experience was opened to a wider audience.

Eight students began as semifinalists, each representing a different Material Advantage chapter. Judging was based on delivery, technical content, organization, and ability to work within the time limit of 6–8 minutes. After points were tallied, the first-place winner was John Romankiewicz of Northwestern University and second place went to Erk.

Pictured is John Foltz from Michigan State University, one of four contest finalists.

Program Reflects Collaborative Spirit of MS&T

MS&T '05 provided the perfect venue to celebrate another collaborative achievement for the four sponsoring societies: the full participation of all four societies in the Material Advantage student program. At MS&T '05, the student members of AIST were welcomed as full members of the Material Advantage program, joining ACers, ASM, and TMS.

Before the technical sessions began and MS&T got into full swing, students from 11 different schools met to share ideas about the activities and fundraising efforts of their individual Material Advantage chapters at the Student Chapter Development Conference. As part of this event, students were introduced to the finer points of networking in a presentation by Dan Thoma of Los Alamos National Laboratory. The interactive session not only encouraged students to network with professional members, but offered specific tips on how to, for example, make an impression on presenters (ask thoughtful questions) and make connections at social events (don't huddle in a large group with other students).

Students also had the option of attending a series of orientation and career tips sessions, and at the end of the day, all students met at the student mixer, where a video presentation officially welcomed AIST students to the Material Advantage program.

EDITORS' CHOICE

The editors of TMS publications select the must-read papers from the latest editions:

Creep Deformation and Fracture, Design, and Life Extension: "A Unified Theoretical and Practical Approach to Creep and Creep Fracture" by B. Wilshire and H. Burt
The θ methodology is shown to extend rather than conflict with the approaches now widely used to analyze creep property sets. In this way, variations in the shapes of normal creep curves are related directly to the deformation and damage processes governing the behavior patterns observed for three precipitation-hardened aluminum alloys, 2124, 2419, and 8090. Within this unified framework, the θ relationships introduce equations that rationalize creep rate and rupture life data through yield stress or UTS measurements at the creep temperatures, without recourse to the empirical terms involved with conventional parametric methods. This paper is part of the MS&T '05 proceedings that cover both the fundamental aspects and engineering applications of creep. This book includes a wide range of papers including creep life prediction, deformation mechanisms, databases for steels, alloy development for ultra-high temperature, and creep of emerging materials. [READ]

Creep Deformation and Fracture, Design, and Life Extension: "Present Status and Future Prospect of NIMS Creep Data Sheet" by K. Kimura
Aiming to produce long-term experimental creep and creep rupture data of more than sixty kinds of creep resistant steels and alloys, the NIMS creep data sheet project has been continued since 1966. The present status of the project and the recent research activities on long-term creep and creep rupture properties are described. Not only creep and creep rupture properties, but also microstructural evolution during creep exposure has been investigated. It is demonstrated that long-term creep strength of ferritic steels is governed by inherent creep strength that corresponds to the strength of the ferrite matrix itself with an equilibrium concentration, as a result of microstructural change. Degradation mechanism and a new life prediction method of long-term creep strength of high chromium ferritic creep resistant steels are discussed. This paper is part of the MS&T '05 proceedings that cover both the fundamental aspects and engineering applications of creep. This book includes a wide range of papers including creep life prediction, deformation mechanisms, databases for steels, alloy development for ultra-high temperature, and creep of emerging materials.[READ]

Creep Deformation and Fracture, Design, and Life Extension: "Alloy Additions for Improved Creep-Rupture Properties of a Cast Austenitic Alloy" by J.P. Shingledecker, P.J. Maziasz, N.D. Evans, M.J. Pollard
A new cast austenitic alloy, CF8C-Plus, has been developed by Oak Ridge National Laboratory and Caterpillar for a wide range of high-temperature applications including diesel exhaust components and turbine casings. The creep strength of CF8C-Plus is much greater than that of the standard cast CF8C and comparable to the highest strength wrought commercial stainless steel alloys. Further alloy modifications typical in some commercial wrought stainless steel alloys are being pursued for increased creep strength, high-temperature stability, and corrosion resistance. The effect of these alloy additions, namely B, W, Cu, and Al, on tensile and creep strength are discussed in terms of the observed microstructural changes. The addition of Cu was found to be beneficial to the creep strength of the alloy while the addition of W had little effect on either tensile or creep properties. The addition of Al, and to a lesser degree B, decreased the tensile and creep strength of the alloy. This paper is part of the MS&T '05 proceedings that cover both the fundamental aspects and engineering applications of creep. This book includes a wide range of papers including creep life prediction, deformation mechanisms, databases for steels, alloy development for ultra-high temperature, and creep of emerging materials.[READ]

Processing and Fabrication of Advanced Materials XIV With Frontiers in Materials Science 2005: Innovative Materials & Manufacturing Techniques: "Micro-Manufacturing: Making Small Things with Small Machines" by K.P. Cooper
Micro-manufacturing is the production of small parts and assembled functional products using small-scale manufacturing machines. The production goal of micro-manufacturing is to be a highly efficient micro-factory, which is capable of fabrication, cleaning, part handling, assembly, and packaging, all in one location. A manufacturing goal is to produce small three-dimensional parts of many materials, such as polymers, metals, composites, and ceramics, with very modest production and low-cost infrastructures. Micro-manufacturing differs from the well-known microelectromechanical systems and complementary metal-oxide semiconductor technologies, which are largely limited to high-volume sub-micron resolution planar (two-dimensional) silicon processes. Moreover, the production facilities for these technologies are elaborate, large and expensive. Recent advances in micro-machining, micro-forming, micro-molding, and micro-assembly techniques have enabled the manufacture of parts a few millimeters in size having features on the order of micrometers. These developments suggest that micro-manufacturing represents a new manufacturing paradigm that will revolutionize the way things are made. This paper is part of an MS&T '05 proceedings volume that contains 30 papers on the processing, fabrication, characterization, and evaluation of advanced materials. The papers are divided into five sections: Composite Materials, Functional Nanomaterials and Micromanufacturing, Intermetallics and Advanced Metallics, Advanced Metallics and Machining, and Metal Forming and Machining.[READ]

Processing and Fabrication of Advanced Materials XIV With Frontiers in Materials Science 2005: Innovative Materials & Manufacturing Techniques: "Materials Issues in Micro-Manufacturing" by D.L. Bourell
Materials play an important role in manufactured goods. They must possess both acceptable properties for their intended applications and suitable ability to be manufactured. This holds true for micro-manufacturing, where parts have overall dimensions less than 1 mm. This article first reviews materials usage in Asian and European research in micro-manufacturing, categorized by manufacturing process. Then specific treatment is given to materials factors unique to micro-manufacturing and different from traditional manufacturing. This paper is part of an MS&T '05 proceedings volume that contains 30 papers on the processing, fabrication, characterization, and evaluation of advanced materials. [READ]

Processing and Fabrication of Advanced Materials XIV With Frontiers in Materials Science 2005: Innovative Materials & Manufacturing Techniques: "Recent Advances in Development of Bulk Metallic Glasses" by O.N. Senkov and D.B. Miracle
Research work conducted at the Air Force Research Laboratory on development of specific criteria for selection of alloy compositions for bulk metallic glasses, which led to discovery of a number of new metallic glasses, is overviewed. Topological principles of glass formation and efficient atomic packing and a representative model for the atomic structure of metallic glasses are discussed. These new theoretical developments allow accurate prediction of concentrations of a wide range of simple and complex metallic glasses. Properties of several new Ca-based metallic glasses, which have recently been produced based on these developments, are also presented. This paper is part of an MS&T '05 proceedings volume that contains 30 papers on the processing, fabrication, characterization, and evaluation of advanced materials. [READ]

Processing and Fabrication of Advanced Materials XIV With Frontiers in Materials Science 2005: Innovative Materials & Manufacturing Techniques: "Recent Advances in Microforming: Science, Technology and Applications" by J. Cao and N. Krishnan
Microparts are commonly defined as parts or structures with at least two dimensions in the sub-millimeter range which are used extensively in electronics and micromechanical products. This paper presents recent findings on micro-extrusion experiments and analysis results of brass (Cu/Zn: 70/30). The authors find that microstructure of brass affects the final deformed pin geometry and frictional force. When an extruded pin has only several grains across its dimension, the pin tends to bend arbitrary. Meanwhile, the friction force experienced a lower friction coefficient when size reduces. This paper is part of an MS&T '05 proceedings volume that contains 30 papers on the processing, fabrication, characterization, and evaluation of advanced materials. [READ]

Processing and Fabrication of Advanced Materials XIV With Frontiers in Materials Science 2005: Innovative Materials & Manufacturing Techniques: "Application of Controlled Mechanical Alloying and Annealing for the Synthesis of Nanocrystalline Magnesium Diboride (MgB2) Metallic Superconductor" by R.A. Varin and Ch. Chiu
The authors report the results of the synthesis of nanocrystalline MgB2 superconducting compound by mechano-chemical reaction followed by post-annealing. The synthesis was carried out by mechanical alloying of elemental crystalline Mg and amorphous B powders in the magneto-mill Uni-Ball-Mill 5. The nucleation of a small amount of MgB2 is initiated after two-step milling for combined 100 h under protective helium gas. Further reaction to form MgB2 is accelerated by subsequent annealing of the milled powder at various temperatures. A well-developed nanocrystalline MgB2 is formed after annealing of the pre-nucleated powder at the 630–650°C range for a few hours. This paper is part of an MS&T '05 proceedings volume that contains 30 papers on the processing, fabrication, characterization, and evaluation of advanced materials. [READ]
