Embodiment 1

[0014] A) Alloy Preparation

[0015] Ti-25Nb-5 Zr-0.2Fe-15Mo alloy, Ti, Nb, Zr, Fe, Mo pure metals are proportioned according to the mass percentage of alloy components, smelted in a high vacuum arc heating furnace, fully stirred, and cast into 100×60×20mm After the ingot is fully cooled, samples are taken to analyze the solid and liquid phase temperature of the alloy by DTA, and homogenization annealing (with Ar gas protection) is carried out in a vacuum furnace. The homogenization temperature is 1000 ℃ and the time is 10h.

[0016] B) Cold Roll Forming

[0017] After the ingot was homogenized and annealed, the surface was machined into a plate with a thickness of 19 mm, and then cold rolled in multiple passes until the final thickness was 2 mm, and the total deformation was 89%.

[0018] C) heat treatment

[0019] After cold rolling, the samples were solution-treated in a box-type resistance furnace. The solution temperature was 800 °C, and the solution time was 2 hours. A...
