Abstract:

The phase-field method is an emerging computational method to predict and model the morphological and microstructural evolution within the mesoscale regime. It describes the microstructural evolution using a set of conserved and non-conserved order parameters which are continuous across the interfacial region. The spatial and temporal evolutions of the parameters are governed by Cahn-Hilliard equation (non-linear diffusion equation) and Ginzburg-Landau equation. The phase-field method can simulate the complex microstructural evolutions concurrently without tracking the interface region. I will introduce about the phase-field method and their applications to the grain growth, particle/boundary interaction and void swelling behavior of 316 stainless steel. Also, the results from the microstructural evolution modeling of the Fe-Cr system with the fundamental input from the CALPHAD approach will be displayed.
