摘要

In the present investigation, friction stir welding of commercially pure aluminum and 304 stainless steel was carried out at varying tool rotational speeds from 200 to 1000?rpm in steps of 200?rpm using 60?mm/min traverse speed at 2 (degree) tool tilt angle. Microstructural characterization of the interfacial zone was carried out using optical microscope and scanning electron microscope. Energy-dispersive spectroscopy indicated the presence of FeAl~(3)intermetallic phase. Thickness of the intermetallic layer increased with the increase in tool rotational speed. X-ray diffraction studies indicated the formation of intermetallic phases like FeAl~(2), Fe~(4)Al~(13), Fe~(2)Al~(5), and FeAl~(3). A maximum tensile strength of ~?90% that of aluminum along with ~?4.5% elongation was achieved with the welded sample at tool rotational speed of 400?rpm. The stir zone showed higher hardness as compared to base metals, heat affected zone, and thermo-mechanically affected zone due to the presence of intermetallics. The maximum hardness value at the stir zone was achieved at 1000?rpm tool rotational speed.
