Abstract

Refractory high-entropy alloys (RHEAs) have outstanding characteristics such as high melting point, high temperature oxidation resistance and corrosion resistance, which shows very promising application in the high temperature field. But commonly the refractory high-entropy alloys have the disadvantages of high density and poor plasticity. In this work, ZrTiHfV_0.5 Nb_0.5C_x (x=0, 0.06, 0.12, 0.2) alloys are prepared by vacuum non-consumable arc-melting with ZrTiHfV_0.5 Nb_0.5 based. The density of ZrTiHfV_0.5 Nb_0.5C_0.2 alloy is reduced to 8.014g/cm³ compared to ZrTiHfV_0.5 Nb_0.5 (8.135g/cm³). The microstructure, static and high-temperature compressive strength are investigated. XRD and EDS analysis show that the microstructure of ZrTiHf_0.5Nb_0.5 C_x alloys consists of BCC phase and HfC phase. ZrTiHfV_0.5 Nb_0.5 C_x alloys have high compression plasticity with plastic strain> 40% at room temperature, no fracture occurs during compression and yield stress is c to 1GPa.
