Experimental investigation on al7020 Fsw joints with interlayer

Abstract

Composites are emerging over the natural or traditional material due to newlinetheir superior mechanical properties and everincreasing range of newlineapplications Moreover the natural materials are inadequate to congregate the newlinefunctionality and capability needs. Henceforth the interest in composite newlinematerials such as Ceramic Matrix Composites CMC Metal Matrix newlineComposites MMC and Polymer Matrix Composites PMC has increased to newlinea great extent Among these MMC has extensively attracted the newlinemanufacturers due to their exceptional engineering properties In MMC newlinealuminium and its alloys play a vital role as matrix phase The major newlineadvantages of such Aluminium Matrix Composites AMC are greater newlinestrength better wear resistance enhanced properties at elevated temperature, newlineexcellent resistance to aggressive environments and lesser weight All these newlineproperties are essential in automotive and aerospace applications in particular newlinetheir larger weight reduction newline newline
