“…In fact, the initial uniform distribution of the reinforcement is not only respected but also improved after joining. Owing to these promising expectations, an increasing number of investigations on the joining of MMCs by FSW have been published in the recent years [1-28].…”

In this research, 8-mm-thick plates of 25%SiC/2124Al composite have been joined successfully by using an un-threaded WC-Co tool which showed minimal tool wear. Decreasing the rotational and advancing speeds is a key factor to obtain successful joints. Defect-free welds, and a joint efficiency (100UTS joint /UTS BaseMaterial ) of up to 97%, can be achieved if a high forge force, F z , (above some 15 kN) is reached. Proportionality between the torque, M, and F z is observed. High F z values, and corresponding M, lead to high values of the total energy per unit length of weld, H tot , supplied by the tool to the workpiece. It is proposed that most of this energy is spent in plastic deformation of the high strength composite.
