Abstract

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°C respectively. Similar to the high entropy alloy, the solid solution of FCC phase is the main constitute part in the alloys. σ 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-xMox is constructed and discussed based on the annealed results. The hardness measurement also illustrates the phase stability of Ni2CrFeMox alloys.
