Will holds a B.S. in Materials Engineering from RPI, a M.S. in Materials Science and Engineering from Arizona State University, and is a Ph.D. candidate in Materials Science and Engineering at the University of Maryland.

In his luncheon lecture, Gerhard Fuchs of the University of Florida will expand on the popular August 2013 JOM article, "Cold War Thriller Brings Classroom Theory to Life." The focus of Fuchs’s talk is Project Azorian, a real-life espionage tale of a lost Soviet nuclear submarine and one of the most ambitious covert engineering feats of the modern age, made even more complicated by a metallurgical failure. Immediately following the luncheon will be a special showing of the theatrical documentary, Azorian: The Raising of the K-129.

Fuchs’s lecture and the documentary screening are open to all TMS2014 attendees.
Advance tickets are required for a reserved table seating and catered lunch.

"Phase diagrams are the beginning of wisdom - not the end of it." This famous quotation coined by Sir William Hume-Rothery has guided the author’s materials research for many years. The main part of this presentation aims at an audience with no prior exposure to phase diagrams and all those interested in "my way" of concisely teaching "How to Read and Apply Phase Diagrams." Starting from the very basics of phase diagrams and phase equilibria, we will go through reading unary, binary and ternary phase diagrams, including liquidus projections, metastable phase diagrams, and useful choices of state variables in phase diagrams. Thermodynamic simulation of Equilibrium versus Scheil solidification is also covered and the path from initial off-equilibrium state towards equilibrium is emphasized. Applications demonstrated include alloy solidification, heat treatment, and soldering. An example "beyond" phase diagrams is given by the competition between thermodynamic and nucleation barrier for secondary phase selection.

Maurits Van Camp is currently director of the recycling & extraction technologies platform at Umicore Group Research and Development in Olen, Belgium. Van Camp graduated from the K.U.Leuven, Belgium, as a material science engineer in 1979 and received his masters in extractive metallurgy from the University of Utah, USA, in 1981. He has over 30 years of research experience in the field of extractive metallurgy. His prime focus has been in realizing breakthrough developments for closing the loop for non-ferrous metals: Pb-Cu-Zn-Ni-Co-As-Se-Te-Bi-Sb-Sn-Ag-Au-In-Ge-PGMs and rare earth metals. 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.

Rare earths metals, including yttrium and scandium, are being increasingly used in clean energy technologies, colored phosphors, lasers and high intensity magnets. There are important defense applications such as fighter jet engines, missile guidance systems and space based satellite and communication systems based on these metals. The commitment to clean energy technologies by governments and the projected growth in power and transportation sectors across the globe ensure that the demand for rare earth metals and compounds would continue to escalate. This demand implies that, to ensure unhindered technological innovation, it is essential to possess secure supply chains for rare earth elements. Therefore, rare earth metals are not rare but critical. The United States continues to be one of the largest consumers and importer of rare earths and the trend is expected to continue as the demand increases. In order to ensure secure rare earth supply and attenuate supply-demand imbalance post 2014, it is not only necessary to encourage and support exploration of newer reserves, build a rare earth stockpile, but it is also of utmost importance to look at opportunities to recycle and reuse Rare Earth Elements from secondary sources, such as post-consumer and manufacturing process wastes. This discourse will describe the technological developments made to convert these valuable resources into functional manufactured materials for lighting industry, automotive and petroleum refining catalysts, and high density permanent magnets.

This talk focuses on designing and processing of novel nanostructured materials of controlled size and orientation, and defects and interfaces (1). Thin film growth modes can be precisely controlled to produce zero- one-, two-, and three-dimensional nanostructures. The orientation control requires epitaxy across the misfit scale which is achieved by the paradigm of domain matching epitaxy. The DME paradigm emphasizes the matching integral multiples of lattice planes across the film-substrate interface, where domains are separated by dislocations and the misfit in between the integral multiples is accommodated by the principle of domain variation. This talk emphasizes two-dimensional psuedomorphic metamaterials where the chemical composition is controlled by growth parameters and the structure is determined by the structure of the substrate which provides a template for thin film growth. The thickness (1-5 monolayers) can be controlled manipulating strain and internal thermodynamic free energy.

Using well characterized thin film nanostructured materials of uniform grain size, we establish unequivocally the phenomenon of inverse Hall-Petch relationship. Process-induced defect content within the grain plays an important role in the onset of inter-grain deformation and resulting grain softening. We show that interfacial energy can be controlled by alloying the boundaries to improve the stability of nanostructured materials, which is critical to practical applications. We also review exciting modifications in mechanical, optical, magnetic and electrical properties of ceramics by embedding metallic nanodots, which incorporate useful properties of metals into ceramics. In-situ deformation studies of these materials shed light on the mechanisms of improvements of fracture toughness and ductility by the incorporation of metallic nanodots. We also show that a combination of nano- and micro-grains plays an important role in designing, processing and obtaining materials with unique and improved properties.

(Gianola) Research and education in science and engineering have no boundaries. Despite geopolitical conflict and a diversity of global cultural influences, science and engineering transcends all and speaks a common language – progress that evolves the frontiers of knowledge and technology. A cultural shift is upon us that we would be remiss not to embrace – according to a recent National Academy of Sciences report, as of 2007, China became second only to the U.S. in the estimated number of people engaged in scientific and engineering research and development. I propose to moderate a discussion on strategies – implemented from the laboratory to governmental policy – to promote rich, engaging, and longstanding global interactions in materials science and engineering. Topics to be discussed include (i) defeating parochial views to research and education, (ii) mechanisms (both present and future) for engagement in international activities, and (iii) opportunities for student exchange and promoting global citizenship in the next generation of scientists and engineers.

(Manuel) Engineering has always provided the backbone and motivational driving force to pursue advancements in materials science. However, in the era of reducing credit hours and declining budgets, it has been difficult to maintain a high level of engineering content within the materials science and engineering (MSE) curriculum. Initiatives such as the Materials Genome and Integrated Computational Materials Engineering (ICME) has proven that science content can be tied to engineering skills in an efficient and streamlined manner without sacrificing quality of either ideology. This talk will focus on methods to overcome the gap created when science and engineering must merge together and showcase examples of successful pedagogical practices that illustrate the idea that integrating design and entrepreneurship further enhances and deepens a student’s understanding of scientific concepts and engineering-based critical thinking.

Dissimilar joints between 1050 Al alloy and Cu were prepared by ultrasonic spot welding technique under various welding conditions to understand the characteristics of joints. Tensile shear strength of the joints increased with increasing the welding energy up to 0.3 kJ. The strength was saturated around 1.3 kN when the welding energy was applied more than 0.3 kJ. The joint welded with sufficiently high energy was fractured at base metal of Al alloy during tensile shear strength test. The interface microstructure in Al alloy consists of severely deformed region due to ultrasonic vibration. In addition, the fine and equiaxed grains were observed near the joint interface in the specimens fractured at base metal. Moreover thin Al2Cu intermetallic compound layer with the thickness of 40 nm was found to be formed at the joint interface in the specimens fractured at base metal.

It is well known that aluminium smelters are one of the main producers of the PFC emissions during smelting process. The PFC emissions are produced during a known event called anode effect. The aluminium industry has recognized this issue and worked on reducing PFC emissions levels over the past several years. At DUBAL, a lot of work has been done in this regard over the past several years which resulted in achieving low PFC emissions. This paper shows the approach taken to reduce PFC emissions, the work done to translate the fundamental understanding of the root causes into practical applications, and finally the changes made to the various systems and practices to cascade the knowledge and changes in the systems and practices to the potlines.
