摘要：
By the 3D coupled thermo-mechanical finite element model of linear friction welding of TC4 titanium alloy,the relation between the temperature and the flashes is researched.The numerical simulation results show that the flashes with the wrinkles appear only when the temperature of material in the friction surface is high enough.The flashes,which are made up of material with high temperature,are squeezed out of the component.The appearance of flashes makes the temperature of material in the friction surface slowly increase or even decrease.Compared with the oscillation frequency and the oscillation amplitude,the friction pressure' s increase can more easily attain the flashes with the bigger dimensions.
