Embodiment 1

[0015] A) Alloy preparation

[0016] Ti-25Nb-5 Zr-0.2Fe-15Ta alloy, Ti, Nb, Zr, Fe, Ta pure metals are proportioned according to the mass percentage of the alloy composition, melted in a high-vacuum arc heating furnace, fully stirred, and cast into 100×60×20mm The billet is fully cooled and sampled to analyze the solid-liquid phase temperature of the alloy by DTA. Homogenization annealing (with Ar gas protection) is carried out in a vacuum furnace. The homogenization temperature is 1000°C and the time is 10h.

[0017] B) cold rolled forming

[0018] After the billet is homogenized and annealed, the surface is machined into a plate with a thickness of 19mm, and then multi-pass cold rolling is carried out until the final thickness is 2mm, and the total deformation is 89%.

[0019] C) heat treatment

[0020] After cold rolling, the sample is solution treated in a box-type resistance furnace. The solution temperature is 790°C, and the solution time is 2.5 hours. After solution, ...
