Abstract: The uneven macrostructure formed in the forging process of titanium alloy is regarded as unqualified in aero engine parts.Using finite element simulation to analyze the forming process of the original process of a TC4 bearing forging.It is found that the original blanking process adopts the bar reverse drawing deformation method to be unreasonable, resulting in large deformation of the core of the forging and small surface deformation of the forging.The low-magnification structure of the forging is uneven.By optimizing the blank making process of forgings and adopting the multi-fire swaging deformation process, the uniformity of the low-magnification structure of the forgings is significantly improved.The content of primary α-phase in the microstructure is increased by 10% compared with that of the original process.The mechanical performance test results show that the room temperature tensile performance distribution after the process optimization is relatively uniform, and the ultrasonic detection meets the requirements of the relevant technical standards.
