摘　　要：采用不同的固溶温度、固溶后冷却速度以及时效温度,通过性能检测、电子显微镜观察,较系统地研究了TC18钛合金热处理工艺对组织和性能的影响。结果表明,于830℃固溶并缓冷至750℃后空冷,然后在600℃时效,锻件的强度和断裂韧性可得到最佳的匹配。By use of different temperatures and cooling rates for the solution treatment as well as aging temperatures, and by the detection of properties and observation through the electron microscope, effect of heat treatment process on structure and property of TC18 titanium alloy has been more systematically studied. The results show that solution treating at 830℃, slow cooling to room temperature and then aging at 600℃ will help the forging to obtain optimum combination of strength with toughness.
