Synthesis and characterization of a new TiZrHfNbTaSn high-entropy alloy exhibiting superelastic behavior

In this study, a new single-phase bcc Ti35Zr35Hf15Nb5Ta5Sn5 high-entropy alloy (HEA) was developed and investigated by means of cyclic tensile tests, transmission electron microscopy (TEM), back-scattered diffraction (EBSD) in situ synchrotron X-ray (SXRD). The reveals superelastic behavior due to the reversible stress-induced martensitic transformation that occurs between ? phase ?'' phase. A high strain recovery 3.8% is obtained test, which attributed <110>?{447}? recrystallization texture observed.
