摘要：

The new TiZrHfNbSc refractory high-entropy alloy was prepared by vacuum arc melting with argon shield. The microstructure were studied by XRD, SEM and DSC, and the hardness and mechanical properties were measured by Vickers microhardness tester and micro-control electronic universal testing machine. The results show that the TiZrHfNbSc refractory high-entropy alloy has a single disordered bcc solid solution structure with the lattice parameter a=0.3443 nm. The alloy density is 7.16 g/cm3 and the Vickers microhardness is 3800 MPa. The alloy has high compression yield strength (σ0.2=650 MPa) and the compression deformation rate is more than 60%. The strengthening mechanism of the alloy is solid solution strengthening. © 2020, Science Press. All right reserved.
