Ti-5523钛合金热变形流变行为的研究 毛柏平1,郭胜利1,沈健1 (1.北京有色金属研究总院加工工程研究中心,北京,100088) 摘要:采用恒应变速率高温压缩模拟实验,对Ti-5523钛合金在应变速率为0.001~5.0 s-1,变形温度为600.900℃条件下的流变应力行为进行了研究,计算了变形激活能及相应的应力指数,建立了合金的应力.应变关系方程.结果表明:在恒温条件下,合金的流变应力随应变速率的增大而增大;在恒应变速率条件下.合金的流变应力随温度的升高而降低;变形激活能和应力指数分别为Q=317.811 kJ·mol-1和n=4.43;可用包含Arrhenius项的Zener-Hollomon参数描述Ti-5523钛合金高温塑性变形时的流变行为. 关键词:Ti-5523钛合金; 热压缩变形; 流变应力; Zermer-Hollomon参数; [全文内容正在添加中] ......

)Abstract:A new cup-drawing process of BT20 titanium alloy was studied. Tensile tests were carried out at room temperature, and then cup-drawing experiments were carried out with conical female die at high temperatures. The results show that the plasticity of BT20 titanium alloy is bad, σs/σb is big, n is small, so it is not suitable for BT20 titanium alloy which draws at room temperature, even......
