Abstract

This articles provides a summary of results of recent research on simulations of interface-controlled phase transformations with the aim of better understanding both the kinetics of these transformations and the resulting microstructure. Atomistic (kinetic Monte Carlo) simulations were performed to gain insight into the atomic (jump) processes occurring during interface movement in the massive austenite → ferrite phase transformation in pure iron. Mesoscopic (geometric) simulations were performed to reach an understanding of the formation of the microstructures resulting from phase transformations which obey specified kinetic models. As a special feature, the effect of non-random nucleation on the transformation kinetics was studied.
