Cast metal matrix composites—challenges in processing and design

Studies on the effect of delayed aging on the mechanical behaviour of AA 6061 SiCp composite

“…The details of stir casting process are reported in detail elsewhere [2,5,13]. The cast billets were hot extruded in four stages at 693 K from the original diameter of 75-17 mm rods.…”

“…The as cast composite has very limited usage due to the inherent deficiencies and hence it is subjected to secondary processing [6,7]. The final stage of the production process of composite materials with aluminium alloy matrices usually includes heat treatment process to modify the matrix microstructure by differential precipitation [8,9].…”

Influence of precipitation hardening parameters on the fatigue strength of AA 6061-SiCp composite

“…Aluminium is lightweight, which is the foremost requirement in most of the applications of MMCs (Lindroos and Tlvitie, 1995;Ray, 1990). Recently there has been an increased interest to use aluminium matrix-based discontinuously reinforced composites (DRCs) for primary structural applications (Kimpson and Swoff, 1989).…”

SiC dispersed polysulphide epoxy resin based functionally graded material

“…Functionally graded materials (FGMs) are unique in properties as the properties of FGM vary in particular direction to serve the desired purpose. The recent advancement in development of FGMs has created interest in using sedimentation or centrifugal casting methods [1][2][3][4][5][6]. Sedimentation and flow induced migration of particles produce concentration profiles that may provide smooth transition in electrical and thermal stresses across the thickness and minimize stress concentration at the interface of dissimilar material.…”
