BTi-421111钛合金是一种低成本中强钛合金，通过研究BTi-421111钛合金薄板冷轧变形量、退火温度等工艺参数对室温力学性能和显微组织的影响，探讨了BTi-421111钛合金薄板冷变形特点及组织性能的变化规律，确定了BTi-421111钛合金最佳的退火温度。研究结果表明：BTi-421111钛合金板材具有较好的冷变形能力，合理的变形量为30％左右，此时板材的抗拉强度为1140MPa，延伸率为11％，强度一塑性匹配良好；最佳退火温度为780～810℃。
BTi-421111 is a kind of low-cost and moderate-strength titanium alloy. The effects of cold rolling reduc- tion, annealing temperature on mechanical property and microstructure at room temperature was investigated in this paper. The cold deformation character and the structure evolution law of BTi-421111 titanium alloy sheets have been summarized. It is found that BTi-421111 has the good perfomrance of cold deformation. The reasonable deformation is approx. 30%. The tensile strength is 1 140 MPa and elongation is 11%. The strength and ductility has good match. The optimal heat treatment is 780 -810℃.
