چکیده
DP600 steel and AA7075-T6 aluminium alloy plates were joined using the friction stir spot welding process. The effects of different tool rotational speeds on mechanical properties, intermetallic compound formation interface microstructure welded joints investigated. highest lap shear tensile load was obtained from samples at a speed 1040 rpm (6.5 kN). It determined that joint decreased with increasing speed. XRD analysis performed broken surfaces, phase to be Al13Fe4. As result Vickers microhardness tests, 1320 1500 rpm, in structure which compounds by analysis, displayed higher hardness values. In addition, when scanning electron microscope images examined, it cracks observed porosity both increased
