Ni1.5CoCuFeCr0.5−xVx (x = 0.25, 0.5 mol) HEAs are synthesized by MA and SPS. Carbon is introduced into the HEAs by the decomposition of process control agent. (V,Cr)7C3 and V2C carbides are observed in the bulk HEAs after SPS. Tiny Carbides (∼130 nm) are distributed in ultra-fine grained FCC matrix phase. Ni1.5CoCuFeCr0.5−xVx alloys exhibit excellent comprehensive mechanical properties.
