摘要：The present contribution focuses on a recently developed model of microstructure evolution.The model is based on a phase-field approach,which takes account of kinetic effects in solidification of alloys and intermetallic compounds.It further incorporates crystal orientation as an additional field variable,which evolves through a Monte-Carlo algorithm.Combination of the phase-field approach with Monte-Carlo algorithm allows for physically meaningful and computationally effective simulation of microstructure in polycrystalline and intermetallic forming systems.The paper includes various examples of simulated microstructures in different thermal processes.
