摘　　要：通过对8型钛合金TM60进行不同制度的固溶时效处理，研究了各制度下其显微组织、相结构和力学性能的变化。研究结果表明：α相的含量和体积分数对合金性能有较大影响，固溶处理温度选择在700℃，时效处理温度应选择在400℃~450℃，β型钛合金TM60具有最佳的强塑性。TM60 alloy of β type titanium was treated on different temperatures with solid solution treatment. Its micro- structure, phase structure and mechanical properties were studied respectively. The result showed that the content of α phase and its volume fraction have significant impact on the plasticity of the alloy. Its plasticity and strength is the finest when treated at 700℃ in solid solution treatment and under a aging process of 400℃ ~450℃.
