摘要	High-entropy alloy (HEA) is an attracting topic raising in materials science and condensed matter physics. Although several types of superconductors have been discovered in HEAs, the critical currents (J(c)) of HEA superconductors require further study. Here, we study the current-carrying ability of (TaNb)(0.7)(HfZrTi)(0.5) HEA at various heat treatment conditions. We obtained the high upper critical field and large current carrying ability, which point to the potential applicability of the HEA superconductor under extreme conditions. Interestingly, the fishtail or the second peak effect was found in HEA superconductors, and the position of the vortex pinning force shows a maximum at 0.72 of the reduced field, which is quite different from the cuprates and iron-based high-T-c superconductors. Together with the resistive measurements, the vortex phase diagram is obtained for the HEA superconductor.
