Effect of Zr content on structure and mechanical properties of (CrTaNbMoV)Zrx high-entropy alloy films

In this paper, the influence of Zr content on the phase formation, morphology, hardness and tribology behavior of (CrTaNbMoV)Zrx films are systematically investigated. The XRD results indicate that the (CrTaNbMoV)Zrx films are evolved from BCC to amorphous phase. The thermodynamic ΔSmix, ΔHmix and VEC of amorphous are similar to BCC structure, while the atomic radius mismatch (δ) of amorphous phase is remarkable large that the values of BCC...
