摘　　要：以10mm厚度的热轧钛合金板TC4为原料,通过Hopkinson压杆实验和强迫剪切实验,对高应变率下的厚板钛合金的塑性行为进行了研究和分析,得到了不同热处理制度下材料的真实应力-应变曲线,并观察了不同热处理制度下试验后材料的微观组织。The TC4 of hot rolling titanium alloy sheet of 10 mm thickness was taken as the raw material in this paper. The plastic behavior of titanium alloy sheet at the high strain rate was studied and analyzed through the Hopkinson compressive bar and forced shear experiments. The material true stress strain curves of different heat treatment mechanisms were obtained. At last the microstructures of tested materials with different heat treatment mechanisms were also observed.
