Experimental investigation on Friction stir welding of Aa6082 zro2 b4c particulates Composites

Abstract

Aluminum Metal Matrix Hybrid Composite (AMMHC) materials are newlineconsidered to be quothigh-techquot materials owing to superior properties like higher newlinestrength, hardness, stiffness, durability, lightweight, better resistance to newlinecorrosion, heat, chemicals, weathering, and their wider applications. AMMHCs newlineare used as either a single component system or welded components in industrial newlineand domestic applications. Among the various welding methods available for newlinewelding AMMHCs, fusion welding has limited acceptance in the industries due newlineto the occurrence of segregation and undesirable reactions between the newlinereinforcement particles and liquid aluminum in the fusion zone. Due to these newlineconstraints, fusion welding processes find it difficult in making AMMHCs newlinejoints. These difficulties are overcome by the solid-state welding processes, newlineparticularly the friction stir welding (FSW) process. FSW process is a type of newlinesolid-state welding technique and it uses a stirring tool for making a strong joint newlineby the generation of heat. In FSW, joining or welding takes place below the newlinemelting point of AMMHC materials and there are no issues such as segregation newlineand undesirable reactions. newline
