Fabrication of Aluminum 5083/SiC Surface Composite on Tungsten Inert Gas Weld Joint by Novel Direct Friction Stir Processing Technique

For the creation of surface reinforcement particles in metal matrix, friction stir processing is frequently utilized. Formation aluminum/SiC composite on Tungsten Inert Gas (TIG) butt weld Al5083 by a novel technique direct (DFSP) using hollow tool successfully demonstrated this present work. Deposition SiC zone DFSP was confirmed X-Ray diffraction (XRD) method. Micro analysis joint achieved metallographic microscope and scanning electron (SEM). Microstructure shows finely distributed aluminum matrix. Absence detrimental intermetallics energy dispersive spectroscopy (EDS) analysis. Tensile strength DFSPed specimen found to be 227.3 MPa which 19.5% lower than UTS autogenous TIG specimen. Microhardness SZ increased from microhardness 86 Hv 107 due presence particles.
