At 500℃,the creep tests were carried out at three stress levels 0.3σ_(0.2)~(500℃),0.4σ_(0.2)~(500℃)and 0.5σ_(0.2)~(500℃)for TB2 titanium alloy solution-treated for 30 min at 800℃,air-cooled to room temperature.The new creep constitutive equations were established based on classic creep constitutive equation and Garofalo creep constitutive equation.The constitutive parameters in three creep constitutive equations were obtained by using Origin to fit the creep experimental data.The new creep constitutive equa...
