Abstract：

TC11 titanium alloy blade is one of aircraft engine important parts,its shape is complex and the quality requirement is high.The warps and the forgings may be discard due to the formed forging's remaining stress and the temperature stress.But it is possible to use the isothermal adjustment process to reduce the warp distortion and make the blade shape to meet the qualified requirements.Three dimensional design software Pro/E was used to carry on the design in view of the uniform temperature adjustment mold,and the mold cavity modeling problem was mainly solved.The three dimensional surface modeling of blade was carried out and the heating and cooling devices for the isothermal sizing die were simultaneously designed.Its design flow is: creating the three dimensional entity of the blade,adding on margin to the blade,using entity to set up the mold cavity,putting on the mold structural elements,and designing heaing and cooling system.
