摘要
通过Gleeble-3500热模拟实验机获得了TC6钛合金在变形温度为800～980℃,应变速率为0.5 ～5s-1,变形程度为30％和60％时的应力-应变曲线.利用高温变形机理分析了热变形参数对流动应力的影响规律,建立了可用于锻造过程数值模拟的TC6合金高温变形的本构方程.
The stress-strain curves for TC6 titanium alloy at the deformation temperature of 800-980℃, strain rate of 0.5-5s-1 ,the deformation degrees of 30% and 60% were obtained through Gleeble-3500 thermal simulation testing machine. The influence of thermal deforma- tion parameters on the flow stess was analyzed through hot deformation mechanism. And then, the constitute relation of hot deformation for TC6 alloy was obtained and used in simu- lation of the forging process.
