摘要：

研究了不同热处理制度对Gr.38钛合金板材显微组织和力学性能的影响。结果表明：低温普通退火处理对Gr.38钛合金板材的组织和力学性能影响不大；两相区固溶时效处理可以大幅度提高Gr.38钛合金板材的抗拉强度和硬度，但其塑性和冲击韧性下降显著；固溶后水冷较空冷可以获得更细的次生α相和相对更少的初生α相，Gr.38钛合金板材的抗拉强度和硬度更高；通过控制时效温度可以调整次生α相的片层厚度，时效温度越高，合金的抗拉强度和硬度越低，塑性和冲击韧性越高。Gr.38钛合金板材具有较好的防弹性能，采用普通退火工艺获得的板材防弹性能最佳。

The influences of different heat treatment systems on the microstructure and mechanical properties of Gr.38 titanium alloy plates were studied. The results show that the low temperature general annealing treatment has little effect on the microstructure and mechanical properties of Gr.38 titanium alloy plate. The tensile strength and hardness of Gr.38 titanium alloy can be greatly improved by solution and aging treatment in two-phase zone, but its plasticity and impact toughness decrease significantly. After solution treatment, finer secondary α phase and less primary α phase are obtained by water cooling than air cooling, and the tensile strength and hardness of Gr.38 titanium alloy are higher. The lamellar thickness of secondary α phase can be adjusted by controlling the aging temperature. The higher the aging temperature is, the lower the tensile strength and hardness of alloy are, but the higher the plasticity and impact toughness are. Gr.38 titanium alloy plate has better bulletproof performance, and the best bulletproof performance is obtained by general annealing process.
