摘　　要：研究了热处理温度对初始等轴组织TC4钛合金显微组织及力学性能的影响。随热处理温度的升高，合金的组织逐渐由等轴态转变为双态和β转变组织，同时其力学性能也随之发生变化。其中热处理温度在950-970℃之间时可获得综合力学性能较好的双态组织。研究结果表明，可通过调节热处理条件实现TC4合金的组织性能调控。The effects of heat treatment temperature on microstructure and mechanical properties of TC4 alloy with equiaxed primary microstructure were investigated. It was shown that the microstructure changed first to α＋β and then β phase with increasing heat treatment temperature, meanwhile the mechanical property also changed. And duplex microstructure with good comprehensive property could be obtained by heat treatment between 950-970 ℃. The results show that the microstructure and mechanical property can be controlled by adjusting the heat treatment temperature.
