Studies on the influence of theInterface characteristics on the stirCast ALSICP and diffusion bonded ALSIC

Abstract

Since the early 1960s there is a demand for new and improved newlineengineering materials with the advance of modern technology and the interest newlinein the areas of aerospace and automotive industries has led to a rapid newlinedevelopment of metal matrix composites The high demand on materials for newlinebetter overall performance has led to extensive research and developmental newlineefforts in the field of composites Among the composites the aluminium newlinebased metal matrix composite materials are widely used To meet this newlineemerging need innovations in materials processing enabled achieving an newlineenhancement in stiffness realization of a high strengthtoweight ratio an newlineimprovement in wear resistance and maintaining strength at elevated newlinetemperatures Jayamathi et al 2004Rajan et al 1998 newlineAluminium based metal matrix composites have been one of the newlinekey research areas in materials science for the last few decades Most of the newlinework has been dealing with aluminium matrix and SiC reinforcement for newlineachieving requiring the light weight in combination with high strength and newlinestiffness This is because aluminium is lighter in weight which is the first newlinerequirement in most of the industries In addition it provides impressive newlinestrength improvement as the thermal expansion coefficient of Al matrix newlinecomposites can be adjusted by using silicon carbide carbon and boron newlinecarbides Lindroos 1995 newline newline newline
