Modelling of microstructure evolution during thermal processes –a hybrid deterministic-probabilistic approach

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.
