摘要：
The extrusion phase of linear friction welding of Ti 6Al 4V, which has been shown to have an important effect on weld integrity, is investigated. The position of the area at the rubbing interface where the maximum frictional heat input develops is shown to depend on the amplitude of oscillation. This is corroborated with macroscopic examination of the flash and axial shortening data from experiments. An analytical model is developed to predict the strain rates that the material at the plasticised zone of the interface is exposed to, using phenomenological experimental data.
