Abstract： The blank and the dies of rheological forming were 3D-modeled based on the software named UG NX3. The numerical simulation research on thermo-rheological forming of the TC11 titanium alloy vane disk with complex shape has been conducted by DEFORM 3D. Under a certain temperature and three kind of different strain rates, the distribution of equivalent strain field, temperature field and load-stroke curves of punch and concave die during the thermo-rheological forming procedure of the TC11 titanium alloy were analyzed, so that its thermo-rheological forming process and parameters were optimized.
Keywords： TC11 titanium alloy; thermo-rheological forming; strain rate; 3D modeling; numerical simulation; DEFORM 3D
