摘要：

The phase stabilities of Ni2CrFeMox(x = 0.1-0.5) multi-principal-component alloys with medium configurational entropy are investigated through long-time annealing at 600, 750, 900 and 1000 degrees C respectively. Similar to the high entropy alloy, the solid solution of FCC phase is the main constitute part in the alloys. sigma phase shows up in the alloys with higher Mo content. The equilibrium solubility of Mo in the solid solution decreases as the temperature decreases. Pseudo binary phase diagram of (Ni2CrFe)(1 -) Mo-x(x) is constructed and discussed based on the annealed results. The hardness measurement also illustrates the phase stability of Ni2CrFeMox alloys.
