In this paper, in order to solve the problem of local heating and local forming of titanium alloy bar, the thermal stress field in the process of titanium alloy heating is simulated and analyzed by finite element method. The influence of temperature field on the internal thermal stress of titanium alloy is discussed. Titanium alloy bar hot heading process design provides a theoretical basis.
