This symposium will focus on evolving understanding and developments concerning the processing, microstructure and properties of intermetallic compounds and multiphase alloys where intermetallic compounds are the major constituents. Topics of interest broadly include: developments in innovative processing from the solid, liquid and vapor states; novel powder related processing technologies (additive manufacturing); next generation alloys (with higher temperature and creep resistance); fundamentals of phase stability and their effects on microstructural design and microstructural degradation in extreme environments/service; physical and mechanical response to various loading conditions and the role of defects in influencing them; impact of integrated modeling on novel approaches of alloy development; advanced characterization techniques on an atomic level (in-situ investigation methods, 3D atom probe) and technological considerations for successful commercial applications. Intermetallic phases of interest include aluminides, silicides, Laves phases, Heusler phases, and various other geometrically- and topologically-close-packed compounds. From an applications perspective, presentations related to intermetallic compounds intended for structural and functional applications, including high temperature use in the aerospace and automotive industries, will be considered. Applications for fossil fuel and nuclear industries, ferromagnetic, catalysis, medical, and thermoelectric power will also be considered.
