Analysis of Hot Deformation Dynamics of TC18 Titanium Alloy
The effect of strain rate and deformation temperature on flow stress of TC18 titanium alloy was studied through heat simulating tests in 760~960℃ with temperature interval and the strain rate interval in 0.01~10s-1.Relationship model of flow stress versus strain was established and hot deformation mechanics of TC18 titanium alloy was analyzed.The results show that the flow stress reduces obviously as the deformation temperature increases or the strain rate decreases.Dynamic recovery occurs at high strain rate above phase transformation point,while dynamic recrystallization occurs at low strain rate as well as at the temperature below phase transformation point.
