It is shown that a set of production and mechanical properties of metastable β-titanium alloys make it possible to produce high-strength parts of a complex shape for aviation equipment. The influence of production regimes for manufacture and hardening heat treatment on structure and mechanical properties of thin-sheet rolled semi-finished products from metastable β-titanium alloy VT47 is studied. It is established that the degree of deformation during cold rolling of sheets due to occurrence of recrystallization processes upon heating to temperatures in the β-region does not significantly affect alloy mechanical properties in a heat treated condition. Varying the aging temperature makes it possible to control the combination of strength and ductility properties of VT47 alloy over a wide range.

结果表明，亚稳β钛合金的一系列生产和力学性能使得生产航空装备复杂形状的高强度零件成为可能。研究了制造和硬化热处理的生产方式对亚稳态β钛合金VT47薄板轧制半成品的组织和力学性能的影响。可以确定的是，由于加热至β区温度时发生再结晶过程而导致的板材冷轧过程中的变形程度不会显着影响热处理条件下的合金机械性能。改变时效温度可以在较宽的范围内控制 VT47 合金的强度和延展性性能组合。
