||Understanding and modeling of phase stability and diffusion kinetics have been a central theme of materials science and engineering with merits in both science and technology perspectives. Advances in computational and instrumentation techniques, cross-scale modeling and novel experimental observations continue to refine our understanding, resulting in design-capable tools for industry and education. This symposium will focus on the temporal and spatial evolution of phase constituents and compositions with due consideration for materials chemistry, processing and applications. Topics of interest for phase stability and diffusion kinetics include: Physics- and mechanism-based theory, modeling and simulations; Fundamental and applications-oriented experimental observations; Microstructural modeling with an emphasis on using fundamental data; Phenomenological expressions and atomistic mechanisms; Methods generation and interpretation of data and databases; Cross-scale models and integration methods.
Of particular interest this year are the various aspects of tracer diffusion studies in unary, binary and multicomponent systems (metals, ceramics, electronic materials). Sessions on tracer diffusion will include: (a) experimental bulk tracer and impurity diffusion studies based on radiotracer, SIMS and other methods in single crystal or polycrystalline matrices; (b) High-throughput tracer diffusion studies, e.g., using diffusion couples, co-deposition methods, etc.; (c) Grain boundary and surface diffusion measurements; (d) Theoretical methods and modeling of tracer diffusivities; (e) Indirect methods to obtain tracer diffusivities using interdiffusion, intrinsic diffusion, sintering, grain growth, coarsening, and other approaches; (f) Application of tracer diffusion data to diffusion formalisms and databases for MGI and ICME initiatives.
Invited sessions dedicated to honor the 2016 J. Willard Gibbs Phase Equilibria awardee will headline this symposium.
