摘要：

For the first time, the numerical simulation to understand the solidification phenomena during suction casting of single-phase six component Fe-Co-Cr-Ni-V-Al FCC HEA is reported here along with the experimental validation and comparison with thermodynamic simulation using CALPHAD approach. The present study elaborates the complete information about solidification behavior, distribution of temperature in metal casting and heat transfer in metal casting and metal-mold interface and mold to the environment and phase transformation mechanism during solidification. The simulated results are validated with the experimental measured hardness using a micro-Vickers hardness tester at 500 g load and the measured hardness of the FCC HEA varies from 220 +/- 2.98 to 259 +/- 5.95 HV. The developed simulation model is in good agreement and acceptable with the experimental results and thermodynamic simulation results.
