抄録	The problems were discussed when a multi-phase filed modeling (MPM) was applied to the weliding phenomena, such as solidification. In order to generate the second phase during solidification, the nucleation principle and place should be decided.Both the enrgy balance search and Neumann rejection method are candidate to overcome the problems. Furthermore, the importance of interafce migrating rate was enhanced. In order to assess the validity of applied interface migrating rate, the usage of in-situ observation technique is useful The importance of in-situ observation method to assess the simulation results was also enhanced in this report. For instance, austenite formation from the delta-ferrite phase in low carbon steel was simulated using MPM and the morphology of microstructure and the interface migrating rate was assessed using LSCM images.
