摘要：

Following a short introduction into multi-phase-field modeling, a short review of applications of the multi-phase-field concept to modeling of solidification of steels is given. Starting from simulations of directional dendritic solidification and peritectic reaction in a simple binary Fe-C system, further extensions to more complex alloys involving e.g. the formation interdendritic MnS or of TiN and to more complex processes are depicted. As a recent example, effects of microstructure features on hot cracking susceptibility in commercial HSLA steel grades are discussed on the basis of multi-phase field simulations. Preliminary results indicate a pronounced effect of precipitates on hot cracking susceptibility.
