Title:Critical nuclei morphology in solid state phase transformations
Seminar:CCMA Luncheon Seminar
Speaker:Lei Zhang (PSU)
We present a diffuse interface (phase field) approach to model the critical nuclei morphology in solid-state phase transformations which has been a long standing problem. We discuss the mathematical properties of a phase field formulation and the numerical algorithms for the computation of critical nuclei in the framework of the calculus of variation. Both analytical and numerical results are provided to show that the phase field approach is able to predict critical nucleus morphology in elastically anisotropic solids without making a priori assumptions.
