Research on Interdiffusion Microstructures at the Interfaces of Multi-Component Alloys

Follows from diffuse-interface approach, and it is straightforward to take different driving forces into account, phase-field modeling has a wide variety of applications on the phenomena of solidification, solid-state phase transformations, fracture etc. High Entropy Alloys (HEAs) have potentially desirable properties as a novel material in materials science and engineering. The inter-diffusion phenomena at the material solidification interfaces are critical for the properties and reliability of a final product. This topic focuses on development of a powerful computational method with the help of Phase-field modeling to reveal the mechanism of inter-diffusion phenomena at solidification interfaces of HEAs.
