Friction welding of cast Fe-28Al alloy

Friction welding of cast Fe-28Al alloy carried out for different times under constant friction pressure, forging pressure, forging time, rotational speeds. Shear strengths and hardness values of weld interface identified and microstructure properties of the welded samples were investigated by optical and scanning electron microscopy (SEM). Experiments results demonstrated that the shear strengths of the welds were higher than the base metal, very close to each other and independent of the process time.
