Date: Wednesday, March 14, 2018
Time: Noon to 2:00 p.m.
Cost: $35 (Tickets can be purchased through the Meeting Registration form)
About the Speaker: Martin Jarrett is the global technical director of the Automotive Structures & Industry business unit of Constellium, holds a master’s degree in metallurgy, and is a chartered engineer and fellow of the Institute of Materials, Minerals & Mining (IOM3). Jarrett was chair of the Light Metals Division of  IOM3 for 14 years. He is also the technical director of the new Constellium University Technology Centre at Brunel University. Jarrett has an extensive background in aluminum extruded products across a wide range of sectors including aerospace and automotive, having worked for Alcan, British Aluminium, Alcoa, Sapa, and now Constellium in a number of senior technical roles in both R&D and operations over a 30-year career in the industry.
About the Presentation: In this talk, Martin Jarrett will discuss how the importance of being innovative and close to their customers is a driving force within Constellium and for their automotive business. This strategy has broken new ground at Brunel University London with the establishment of the Constellium University Technology Center (UTC). This center, a first of its kind in the industry, aims to bridge the gap between fundamental research and series production. A key feature of the work of the UTC will be the rapid prototyping of extruded profiles and components to enhance strength and crush performance limits. A "copy and paste" approach to technology transfer and industrialization will then provide the opportunity to significantly compress development times to series production. The UTC will have a powerful armory of hardware to deliver on its promise of advanced technology and shorter times to market. The opening of the first phase took place in April 2016, with the commissioning of a full-size extrusion press and associated billet casting facilities. Phase 2 will be operational in Q1 2018 and will consist of novel forming and joining technologies in order to produce full-size component prototypes. This presentation will showcase the equipment and some of the key projects being developed, with a critical focus on the application of high-strength 6xxx alloys for the light weighting of structural automotive parts.

Extraction & Processing Division Distinguished Lecturer

Lecture Title: "The Revolutions Ahead in Pyrometallurgy"
Date: Monday Morning, March 12, 2018
Speaker: Geoffrey Brooks, Swinburne University of Technology
Abstract: The pyrometallurgical production of metals has undergone major technological development over the last fifty years. However, important technological and scientific challenges remain, in particular in developing high productivity routes to light metals and in utilizing renewable energy in metals production. There has been considerable progress in developing new pyrometallurgical routes for aluminum, magnesium, and titanium over the last decade. The presenter and his co-workers have made significant progress in developing a new carbothermic route to magnesium and in evaluating alternate routes to aluminum. In this work, a combination of computational modelling techniques and novel laboratory apparatus has been used to test and optimize new process concepts. In designing a supersonic quenching apparatus for magnesium vapors, models that combine computational fluid dynamics and condensation kinetics were used to optimize the design. This combination of modelling and novel laboratory scale testing is also evident in the presenter’s works on developing solar thermal routes to metals production, where a unique solar simulator has been developed for testing reactor concepts. Research groups in Europe and North America have been combining both challenges by researching solar thermal routes to light metals production.
​About the Speaker: Geoffrey Brooks has been a professor of engineering at Swinburne University of Technology since 2006. He was previously a senior principal research scientist at CSIRO (2004-2006), an associate professor at McMaster University (2000-2004), and a senior lecturer at the University of Wollongong (1993-2000). Since completing his Ph.D. at the University of Melbourne in 1993, he has published more than 200 papers and run many projects with companies and government agencies. Brooks has worked extensively on fundamental aspects of steel, aluminium, magnesium, zinc, copper and antimony production. Much of his work has focused on process kinetics, particularly developing process models for optimizing metallurgical processes, such as his team's work on modelling of Zinc fuming for top submerged lance processes. He has also been active in process development, leading a team at CSIRO that successfully developed a new carbothermic route to magnesium. In addition to his research, he has delivered courses and lectures around the world, including in the USA, Canada, UK, Netherlands, Korea, Japan, China, Indonesia, and India.

William Hume-Rothery Award

Lecture Title: "Computational Thermodynamics of Materials and Its Applications"
Date: Monday Morning, March 12, 2018
Speaker: Zi-Kui Liu, The Pennsylvania State University
Abstract: Thermodynamics is a science concerning the state of a system, whether it is stable, metastable or unstable, when interacting with the surroundings. Computational thermodynamics enables quantitative calculation of thermodynamic properties as a function of both external conditions and internal configurations, in terms of first and second derivatives of energy with respect to either potentials or molar quantities. In this presentation, the author’s experience on thermodynamics and computational thermodynamics will be discussed along with their applications, particularly the calculations of thermodynamic properties at finite temperatures and diffusion coefficients using density functional theory, the usefulness of Maxwell relations among the second derivatives in predicting critical phenomenon, and materials design. The significance of second derivatives with respect to one molar quantity and one potential will also be examined. Finally, the author’s perspectives on challenges and opportunities in computational thermodynamic will be presented.

Institute of Metals/Robert Franklin Mehl Award

Lecture Title: "Biological Materials Science: Challenges and Opportunities"
Date: Monday Morning, March 12, 2018
Speaker: Marc André Meyers, University of California, San Diego
Abstract: Biological materials science is a new and vibrant field of materials science and engineering. Although biologists have been studying organisms for centuries, it is only recently that materials scientists have started to use their fantastic experimental, computational, and analytical arsenal of tools to reveal new features. We present the Arzt heptahedron, which defines seven unique and defining characteristics of biological materials. The plethora of different structures and mechanical properties of biological materials is systematized through a new paradigm: eight structural design elements, which are motifs appearing on different species and scales, and which enable analytical treatment and lead to enhanced understanding. We have applied this approach to approximately twenty different organisms. We illustrate our approach by applying this knowledge to the toucan beak, rabbit and pig skin, fish scales, and feathers. It is fascinating to see that characterization techniques such as optical, transmission and scanning electron, and atomic force microscopy, SAXS, Micro and Nano CT, and mechanical testing techniques such as nanoindentation, tensile and compressive testing are helping us to better understand these complex structures. Current efforts at bioinspired materials and designs are also discussed.

Lecture Title: "Advanced Study on Complex Hydrides for All-Solid-State Secondary Batteries"
Date: Tuesday, March 13, 2018
Speaker:
Atsushi Unemoto, Hitachi Ltd.
Time: 3:55 p.m. to 4:15 p.m.
Abstract: Recently, complex hydrides, possessing fast ionic conductivity and electrochemical stability, are considered as a new electrolyte family for all-solid-state lithium rechargeable batteries, beyond the classical oxide and sulfide electrolytes. Unemoto's research group first succeeded in operation of all-solid-state battery that uses a LiBH4 complex hydride electrolyte together with a TiS2 positive and a Li negative electrodes in 2014. The study was then extended to enhance its energy density. A high-capacity sulfur positive electrode, exhibiting an order greater capacity than conventional oxide positive electrodes, was then incorporated into the all-solid-state battery. High discharge capacity of over 730 mAh g-1 was successfully demonstrated for 45 cycles. Additionally, operation of high-temperature durable all-solid-state batteries was successfully demonstrated at 423 K, as a result of an industry-academia partnership project between Tohoku University and Hitachi, Ltd. In the given presentation, R&D history related to complex hydride electrolytes and their battery application will be reviewed.
