Influence of Silicon on Performance of Al/SiC Composites

Abstract:

Silicon is an important alloying element in Al alloys because the presence of Si improves the hardening strength of Al alloy and improves the wetting between the matrix and the reinforcement. In the present study, Al/SiC bonded specimens were fabricated by means of different temperatures and holding times. The microstructure of the composite was examined by scanning electron microscope. The concentration of Si elements at the interface region was observed by EDS techniques and diffusion of the Si elements in the matrix region was calculated by the Arrhenius equation. The hardness test was performed at the interface region. The results revealed that processing temperatures and holding times influences the concentration of Si and the hardness values near the interface region. Keywords: Al/SiC Interface bonding; SEM; EDS analysis; Micro hardness
