Refractory high-entropy Mo0.5NbHf0.5ZrTi alloy matrix composite with MC-carbide particulates-reinforced
was prepared by arc melting. It is found that Mo0.5NbHf0.5ZrTiC0.1 and Mo0.5NbHf0.5ZrTiC0.3 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 C0.1 and C0.3 alloys while the
compressive plasticity is improved slightly due to the decrease of solution strengthening for the matrix
BCC disordered solid solution phase.
