After solution treatment at 1000 °C, the (TiZrHf)50Ni25Co10Cu15 HESMA still contained Ti2Ni-like second phase and (Ti, Zr, Hf) carbide, and thus was not a single solid solution. It exhibited a broad transformation temperature range with Ms = 36.0 °C and Mf = −80.4 °C. In a three-point bending test, the (TiZrHf)50Ni25Co10Cu15 HESMA showed a reversible strain of 4.8% under 650 MPa, which is similar to the performance of Ti50Ni50 alloy but with a much higher output work density.Differential scanning calorimetry (DSC) | High entropy alloy | Martensitic phase transformation | Shape memory alloys (SMA) | X-ray diffraction (XRD)Shape memory characteristics of (TiZrHf)<inf>50</inf>Ni<inf>25</inf>Co<inf>10</inf>Cu<inf>15</inf> high entropy shape memory alloy10.1016/j.scriptamat.2018.11.023https://api.elsevier.com/content/abstract/scopus_id/850564502182-s2.0-85056450218WOS:000457664900040
