Effect of heat treatment process on mechanical properties and microstructure of FeAlCoCrNiTi0.5 alloy
In order to study the effects of different sintering processes on the properties of the alloy, including the microstructure, hardness, friction and wear properties of the alloy, the optimum sintering method and process parameters were selected. A series of FeAlCoCrNiTi0.5 high-entropy alloy blocks were prepared by mechanical alloying using inert alloy sintering technology. XRD pattern showed that when the sintering temperature was 1000°C and the holding time was 3h, the phase structure would be a simple body-centered cubic BCC2 phase and a face-centered cubic FCC phase. SEM observation showed that the microstructure is denser, and the grain refinement of the high entropy alloy is remarkably better. The evaluation of hardness, friction and wear properties showed that the high-entropy alloy had the best overall performance.

Abstract
In order to study the effects of different sintering processes on the properties of the alloy, including the microstructure, hardness, friction and wear properties of the alloy, the optimum sintering method and process parameters were selected. A series of FeAlCoCrNiTi0.5 high-entropy alloy blocks were prepared by mechanical alloying using inert alloy sintering technology. XRD pattern showed that when the sintering temperature was 1000°C and the holding time was 3h, the phase structure would be a simple body-centered cubic BCC2 phase and a face-centered cubic FCC phase. SEM observation showed that the microstructure is denser, and the grain refinement of the high entropy alloy is remarkably better. The evaluation of hardness, friction and wear properties showed that the high-entropy alloy had the best overall performance.
