the equiatomic.tiNbZrtahf alloy was suc.essfully rolled at room temperature with the reduc.ion of ~ 85%. the mic.ostruc.ure and tensile properties were investigated after c.ld working and annealing. It was determined that the rec.ystallization temperature of the tiNbZrtahf alloy between 850 and 900 ℃. c.mplete rec.ystallization and normal grain growth oc.urred, the high stability of single phase was maintained after annealing at 1000, 1200, and 1400 ℃. But the prec.pitated phase appeared after long term annealing, as seen after 500 h at 1000 ℃. After c.ld working, the tensile strength and the elongation of tiNbZrtahf were 1137 MPa and 25.1%, respec.ively. the annealed alloy has a high tensile strength (σ_(b )= 863 MPa) and duc.ility (ε_(e )= 28.5%). Moreover, the oxidation of tiNbZrtahf alloy at elevated temperatures has a signific.nt impac. on its mec.anic.l properties. the poor oxidation resistanc. of tiNbZrtahf c.n ac.elerate tensile failure by induc.ng frac.ures at grain boundaries.
