Title
Phase Field Modeling Of Interdiffusion Microstructure In Ni- Cr-Al Diffusion Couples
Abstract
A phase field model was developed and employed to simulate the interdiffusion microstructure evolution in Ni-Cr-Al diffusion couples. Utilizing the thermodynamic and kinetic data for the Ni-Cr-Al system, simulations of multi-phase (fcc-γ vs. γ + B2-β and γ+β vs. γ+β) diffusion couples were performed. The model predicted the dissolution of β phase in γ vs. γ+β diffusion couples, where the dissolution rate was dependent on the alloy compositions. No dissolution was predicted for γ+β vs. γ+β couples. The simulations results were found to be in good agreement with reported experimental observations in literature.
