Abstract

Hybrid Composite with improved mechanical and chemical properties are widely used in aerospace and automotive applications. Very high strength to weight ratio is the main reason why Aluminium hybrid metal matrix composites are widely manufactured and also used in structural application because of its low cost. Subsequently a lot of research has taken place in AMC with addition of reinforcements to aluminium like boron carbide, alumina (Al2O3), Silicon carbide(SiC) and fly ash etc. Present review was carried out to bring out the latest developments taken place in AMCs and effect of reinforcements. Influence of mechanical & tribological behaviour of aluminum matrix composite has been covered. This study is focused on Al2024 alloy due to commercial easy available and it’s widely used for structural purpose in manufacturing sectors. From the present work, it is clearly observed that lot of research has been carried out on addition of alumina, silicon carbide, boron carbide and fly ash to improve the hardness,tensile, yield strength,wear resistance, machinabilty, good abrasion resistance, high creep resistance, very good dimensional stability, very good stiffness-to weight ratio,strength-weight ratios and enhanced high temperature performance. Making (fabrication) of these advanced engineering materials through stir casting is considered in the present paper.
