Abstract

Refractory high-entropy Mo_0.5NbHf_0.5ZrTi alloy matrix composite with MC-carbide particulates-reinforced was prepared by arc melting. It is found that Mo_0.5NbHf_0.5ZrTiC_0.1 and Mo_0.5NbHf_0.5ZrTiC_0.3 alloys consist of one disordered body-centered cubic (BCC) solid solution phase as the matrix phase and MC carbide phase. MC carbide is enriched with Zr and Hf due to the higher binding strength and without any Mo. Noticeable strengthening from the carbide is not observed for C_0.1 and C_0.3 alloys while the compressive plasticity is improved slightly due to the decrease of solution strengthening for the matrix BCC disordered solid solution phase.
