Study of friction stir butt welding between thin plates of AA5754 and mild steel for automotive applications
In the present study, the feasibility of joining 2 mm thick plates of AA5754-H114 to mild steel was examined. Sound friction stir dissimilar butt welding was achieved between thin plates of the automotive grade 5754 aluminum alloy and mild steel for the first time. Moderate rotational speed and a rather slow traverse speed were used. The mechanical properties of the weld were close to the equivalent of the aluminum base metal and a rise in the microhardness of the weld nugget of around 40% compared to the equivalent of the mild steel base metal was presented. An interdiffusion layer with a width of around 5 μm was created at the interface of the two alloys, the extended width of which probably affects positively the mechanical properties of the welds.
