Title
Phase Field Modeling Of Interdiffusion Induced Microstructure Evolution Under Different Driving Forces
Abstract
Interdiffusion induced microstructure evolution in binary multi-phase alloys was investigated using a phase field model under both isothermal condition and temperature gradient. First, the model was used to simulate microstructure evolution in diffusion couples of Ni-Al alloy system containing P(fcc) vs. P+PQ(L12) phases under isothermal condition. Dissolution of the PQ phase in the two-phase region was well predicted by the model. Second, a new phase field model was devised and employed to investigate the effect of thermotransport or diffusion under a temperature gradient in single-phase and multi-phase alloys of a binary system. Simulation results show that an applied temperature gradient can cause significant redistribution of constituents and phases in the alloy. In multi-phase alloys, the thermomigration effect can cause the formation of single-element rich phases at the cold and hot ends of the alloy.
