| Abstract Scope |
Diffusion multiples have been employed for about 25 years to perform high-throughput and reliable measurements of phase diagrams, diffusion coefficients, and composition-dependent properties including thermal conductivity, specific heat, thermal expansion, magnetic properties, hardness, and elastic constants. The data so obtained have been reliable input to CALPHAD modeling over the years for several alloy systems. Dual-anneal diffusion multiples yielded vast amount of precipitate microstructure as a function of composition, temperature, and time; and will be an opulent ground for coupled experimental-modeling studies to advance the precipitation modeling, including sequential precipitation of multiple phases. A potpourri of my favorite experiments will be shown to illustrate the power of diffusion multiples as input to CALPHAD. Future prospective will also be touched upon, especially in relation to the integration of modeling and experiments. |
