TC11钛合金的高温蠕变实验研究
Experimental Research on High Temperature Creep of TC11 Titanium Alloy
【摘要】 对TC11钛合金在同一温度(550℃)不同应力水平条件下进行了多组蠕变实验,根据有关流变模型建立了积分型蠕变本构方程和微分型应力应变本构关系,并对由蠕变方程推导的理论结果与实验结果的误差进行了分析。
【Abstract】 The creep experiments under high temperature(550℃) with different stress levels have been done on TC11 titanium alloy. The integral creep constitutive equations and differential stress-strain constitutive relationship can be established according to the relevant rheological model. Besides, the error between the results conducted from the theory of creep equations and that obtained from the experiments has been analyzed.
