Simulating interdiffusion microstructures in Ni-Al-Cr diffusion couples: a phase field approach coupled with CALPHAD database

We develop a method for phase field modeling of interdiffusion microstructures in Ni-Al-Cr by linking directly the free energy and mobility data to available databases by the CALPHAD method. Its applications are demonstrated for microstructural evolution in gamma + beta/gamma and gamma + beta/gamma + beta diffusion couples. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd.
