Abstract
A 3D finite element analysis model of inertia friction welding of FGH96 alloy is established by using the DEFORM software. The change of axial shortening of weldment and the material plastic flow behavior are studied. The results show that the change extent of axial shortening and the material flow velocity in friction surface increases first and then decreases with the increase of welding time. After the welding process reaches the stable state, when the welding process reaches stable the material near the two edges of friction surface flows towards the outside of friction surface, while the direction of material flow near the middle of friction surface is mainly the same as the rotational direction of weldment.
