Study of Solidification Microstructures of Multi-Principal High-Entropy Alloy FeCoNiCrMn by Using Experiments and Simulation

Article Preview

Abstract:

The microstructures and the solidification processes simulation of multi-principal high-entropy alloy FeCoNiCrMn were studied by using both experimental and computational approaches. The microstructures were identified by methods of XRD, SEM and EDS. The solidification process was simulated by Scheil-Gulliver solidification model. The alloy mainly forms a single FCC solid solution, but Mn atoms, as well as Ni atoms tend to be enriched in residual liquid phase during the solidification process. These atoms show interdendritic segregation. Present experimental results and computational results are supported each other well.
