Forging Process Optimizing Method for Titanium Alloy Blisk Based on Hot Working Map
Through hot compression simulation tests of TC11 alloy,the strain rate sensitivity factor of the alloy was calculated.The hot working map of the alloy was established.An optimizing method for the forging process of titanium alloy blisk was proposed based on the hot working map.The forging process for TC11 alloy blisk was optimized by using the proposed method.An optimal process was verified by simulation and experiment.The results show that the optimal process is reasonable,by which the duplex structure can be obtained to meet the property requirements of the blisk.
