The effect of Fe content on the phase constituent, microstructure and mechanical properties of Cr Mo VNb Fexhigh-entropy alloys were investigated by using of XRD, SEM, EDS and microhardness tester. The results reveal that Cr Mo VNb Fexalloys exhibited as a solid solution of single bccphase without Fe, whereas bcc solid solution+ intermetallic σ phase was observed with the increase of Fe content. The as-cast alloys show a microstructure with typical casting dendrites. It was found that Mo mainly exist in the...
