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 performance of this type of forging piece is better than that of the piece being made by the common method.The material utilization of this type of forging piece is improved to 60% compared to that of the common forging.The stress,strain and the metal flow inside workpiece during the forming process of the forging piece are understood by software simulation,which provides a theoretical base for process design and equipment selection.
