Abstract:

Friction Stir Welding (FSW), a solid state joining technique, is widely being used for joining Al alloys for aerospace, marine automotive and many other applications of commercial importance. FSW trials were carried out using a vertical milling machine on AL6061\Sic particles. In this study, AL6061\Sic particles plates were welded as similar alloy joints using (FSW) processed.In order to investigate the effect of rotation speeds 710, 910, 1120 and 1400 RPM and travel speeds 16 and 20 mm/min on mechanical properties and microstructure.The mechanical tests were carried out in the welded areas. Vickers hardness profile and tensile tests of the joints as a metallurgical investigation, Optic Microscopy were used for base and weld zones. The results obtained through FSW weld efficiency decreases with increase the volume fraction of SiCp.
