Development of aluminum matrix composite with hybrid reinforcement using stir casting route

Abstract

Aluminum matrix composite (AMCs) has widely utilized in various industries such as automotive, aerospace maritime, electronics components, sports equipment. AMCs is considered as potential materials due to their excellent mechanical and physical properties. The aim of this work is to investigate effect of the addition SiC and fly ash on mechanical properties of AMCs. In this study, AMCs is fabricated using stir casting method with SiC (8 wt%) and Fly ash (0 wt%, 4 wt%, 8 wt% and 12 wt%) as hybrid reinforcement. Aluminum alloy was heated above its melting temperature in the steel crucible and poured into steel mold at 700°C with mixing speed of blade and mixing time are 350 rpm and 400 S, respectively. Mechanical properties of AMCs samples were characterized using tensile test, hardness test and impact test. Mechanical properties test reveals that AMCs with composition 12 wt% fly ash and 8 wt% SiC has maximum value in term of tensile test (15,859 kgf/mm2), impact test (10,22 Joule) and hardness test (57,15 BHN).
