抄録

The mechanically mixed layer at a weld interface and the mechanical properties of dissimilar welded joints of 5052 aluminum alloy to 2017 aluminum alloy, which were made by using a brake type friction welding machine were examined with different welding conditions. The mechanically mixed layer is formed on the friction process, and it is observed at a weld interface all over. The thickness of the mechanically mixed layer decreased with increasing friction pressure, the mixed layer of the outside of joint became thinner than that at the center. The tensile strength of joints which were made with the friction pressure of above 45 MPa, which had an average thickness of 200 μm in mechanically mixed layer, showed 85% of 5052 aluminum alloy base metal. The breakage occurred at the softened area of 5052 aluminum alloy side. The impact strength of joints, which had an average thickness of 200 μm in mechanically mixed layer, were 70% of 5052 aluminum alloy base metal.
