Abstract

High-entropy alloys are a new class of alloys, and attract much attention due to their unique properties. Since the discovery of a superconducting high-entropy alloy (HEA) in 2014, the materials research on HEA superconductor is a hot topic. We have found that Hf₂₁Nb₂₅Ti₁₅V₁₅Zr₂₄ body-centered-cubic (BCC) HEA is a new superconductor with the superconducting critical temperature Tc of 5.3 K. We briefly discussed the comparison of cocktail effect of Tc among BCC HEA superconductors.
