Herbert, M.A.Shettigar, A.K.Nigalye, A.V.Rao, S.S.2020-03-302020-03-302016IOP Conference Series: Materials Science and Engineering, 2016, Vol.114, 1, pp.-https://idr.nitk.ac.in/handle/123456789/8364The application of Metal Matrix Composites (MMCs) is restricted by the availability of properly developed fabrication methods. The main challenge here is the fabrication and welding of MMCs in a cost effective way. In the present study, synthesis of AA6061-4.5%Cu- 10%SiC composite was done by stir casting method. The joining of MMCs was performed by Friction Stir Welding (FSW) using a combination of square and threaded profile pin tool (CSTPP). Further, the welded composite was evaluated for microstructure and joint properties. The microstructural characterization showed uniform distribution of refined fine grains and numerous small particles at nugget zone. The hardness at the stir zone is higher than that of the base material. The tensile test revealed 96% joint efficiency in transverse direction. � Published under licence by IOP Publishing Ltd.Book chapter
