Abstract
The history and future will be presented for modern Additive Manufacturing (AM), also known as 3D Printing. The technology, divided into seven categories by ASTM, dates to the 1980s, although precursor processes and AM "prehistory" date to the 1950s and the previous century, respectively. A rationale will be presented for the use of AM processes in lieu of conventional manufacturing processes. Two requirements for parts under consideration for AM are complex geometry and low production runs. Current sectors using AM illustrate the results. A survey of materials for AM will be provided. Some consideration will be presented respecting where AM technology is headed.

Abstract
The discussion will be directed toward mature safety cultures and how today the envelope of protection involves all levels of management. Safety systems need to capitalize on the approach that multiple tiers are necessary to protect at-risk workers. The talk will focus on protection of the employees beginning with employee empowerment . . . and taking advantage of everything we can for the right purpose. Core to leadership is the understanding that it's not just about doing things right but doing the right things. The same theme is core to accident prevention.

Abstract
The U.S. government has launched a new National Network of Manufacturing Institutes designed to be a public-private partnership aimed at improving domestic manufacturing competitiveness. Four of these institutes have been awarded and several more are planned. Each institute is focused on a particular advanced manufacturing technology and will serve as the bridge between basic research and final product commercialization. The institutes are designed to link a network of universities and national/federal laboratories with companies in a targeted industrial sector. The companies range from small and medium enterprises to large suppliers and OEMs.

This talk will describe how these institutes are operating using the American Lightweight Materials Manufacturing Innovation Institute (ALMMII) as an example. ALMMII is focused on the land, sea, and air transportation sectors, both commercial and defense. The mission is to provide technology solutions that will make the transport of people and goods more sustainable in terms of energy, the environment, safety, and affordability. Reducing weight is a key enabler for meeting these challenges as well as increasing payload and improving performance. In addition to developing new manufacturing processes, ALMMII is also working to develop a prepared and eager metals processing workforce.

He has been instrumental in the make-over of Umicore Precious Metals Refining through his involvement in the introduction of breakthrough technologies such as the Cu smelter, the precious metals concentration plant, and the rechargeable battery recycling process. Within his research, the minimalist approach of Prof. Jaikumar has been the underlying philosophy for developing, realizing, and implementing breakthrough developments.

Abstract
In the metal product value chain from mined ores → concentrates → oxides → metals → alloys → finished products, the most energy-intensive step is usually the oxide to metal conversion. Today's industry generally uses carbon and large amounts of energy to reduce oxides to metals, resulting in significant pollution. This talk will describe an energy efficient and environmentally friendly metals production technology that utilizes oxygen-ion-conducting solid oxide membranes (SOM) to electrolyze metal oxides dissolved in a flux and directly produce the desired metal and pure oxygen gas as a value-added byproduct. The process has been successfully used to demonstrate production of technologically important metals from their respective oxides. These include light structural metals (aluminum and magnesium), solar-grade silicon, critical rare earth metals (dysprosium and ytterbium), and corrosion-resistant metals (titanium and tantalum). The electrochemical performance of the SOM cell for the production of several of these metals will be presented.

Abstract
Every leap in human civilization is associated with a material—think of the stone-, bronze-, and steel-ages. Even though the current era is referred to as the information age, it would be apt to call it the Materials Age because materials have played a crucial role without which the information age may not have been feasible. To illustrate the role of materials science in microelectronics, we have chosen the following examples:

Past Role
   • Zone refining
   • Growth of bulk silicon crystals

Present Role
   • Reduction of dislocations in III-V crystals
   • Degradation behavior of light emitting devices

Future Role
   • Integration of dissimilar materials: two step-step epitaxy of GaN (0001) sapphire
   • High temperature electronics

Since advances in materials are generally accentuated by technology needs, the field has a bright future.

Abstract
The early 21st century is experiencing a formidable challenge related to materials extraction and processing. Those core industrial activities will have to ultimately provide more than 9 billion inhabitants with commodities such as steel or fertilizer at an unprecedented rate, while mitigating environmental or societal impacts. In that perspective, higher education institutions have the mission to prepare students to shape the technological paradigms for such challenges, and Allanore argues that it all starts with the fundamentals of materials extraction, metals in particular. Allanore will present his recent endeavor in teaching the fundamentals of chemical metallurgy to undergraduate students at the Massachusetts Institute of Technology, prior to opening a discussion on the possible future of such classes in connection with online education.

Abstract
Wondering how a young person—a freshly graduated high school student—chooses his or her field of study in college, Hosemann always asks new students: "Why did you choose your field of interest? Why material science?" Common answers are that someone in the student’s past mentioned it previously or works in a related field or that the student had a teacher or college advisor who guided them in making the selection of the field of study. But why and how would a student who is not exposed to a good engineering background choose materials science, a field not widely accessible in pre-college education?

While physics and chemistry are often featured on public platforms, such as newspapers or TV, and engineering is in every student’s life through the use of engineered items, such as phones and cars, material science utilizing physics and chemistry to enable engineering solutions is often not on a student’s mind when choosing scientific disciplines or career paths. While this topic is of immediate interest to academics, it bridges further towards a general public perception of what is needed in everyday life to make devices work. In this talk, the question above will be discussed by asking "What do material scientists do?" in a nonprofessional fashion in order to give thought for outreach activities.

Abstract
When maraging steel is austenitized, the reversion from martensite to austenite takes place via diffusionless shear mechanism (martensitic reversion). It is thought that the austenite formed by martensitic reversion (martensitically reversed austenite) contains high-density lattice defect. However, it is impossible to observe martensitically reversed austenite directory, because austenite is unstable at ambient temperature in maraging steel. In this study, we focused on a high austenite stabilization effect of carbon and an austenite stabilizing heat treatment consisting of three-step solid-solution annealing was applied to a 18%Ni-C steel. As a result, martensitically reversed austenite remained fully stable at room temperature through the unique heat treatment. After some microstructural characterizations, the following were mainly found. The martensitically reversed austenite has a fine lath structure with high dislocation density inherited from the lath martensite. While, the crystallographic texture of the austenite was the same as that of the original austenite before martensitic transformation.
