| Abstract: | The isothermal forging process of TC4 titanium alloy was studied during the experiment.One type of DEFORM-3D element analytical software was used to simulate TC4 titanium alloy isothermal forgings process.The results show that the isothermal forging process is effective to forge out a complex titanium alloy piece,the profile of the piece is clear,the surface is smooth and clean,and it has a high dimensional accuracy.The metal streamline distribution of the forging piece is reasonable.The structure performan... |
