Description
Friction stir welding (FSW) was employed to fabricate dissimilar joints between 1060 aluminium alloys and commercially pure Cu under various process conditions and microstructure and mechanical properties studies were conducted to investigate intermetallic compound formation at the interface and in the nugget zone. Specimens were butt welded using a gantry FSW machine with a tool made from heat-treated tool steel. The process conditions comprised rotational speeds of 600-1000 rpm at a constant welding speed of 100 mm/min and welding speeds of 100-300 mm/min at a constant rotational speed of 600 rpm. Microstructure was observed by optical microscopy, SEM and energy dispersive spectroscopy. Vickers microhardness measurements and tensile tests were conducted on transverse tensile specimens.
