摘要: In order to seek the reasonable Laser forming process parameters of TC4 titanium alloy, and to control forming quality, based on the element life and death technique of finite element methods (FEM), detailed numerical simulation of single track and multi-layer temperature field of TC4 titanium alloy during laser rapid forming was conducted with ANSYS parametric design language (APDL). And get the distribution of temperature field and temperature gradients. The calculated results show that the distribution of temperature field changed with the movement of laser beams and the heat affected area have been expanded along with the increase of the scanning time, temperature increase gradually and temperature gradients obviously changed in molten pool area. The temperature gradients in sample are mainly along deposition direction. In the end, carry on an experimentation research testing and verifying according to the simulation parameters, proof that the results can meet the actual situation analysis results, and forming a sample with good performance.
