Abstract – Today the MMC’s have find wide applications in all the engineering fields due to their light weight and high strength parameters, especially in the field of automobile and mechanical industries The aluminium MMC have got wide applications due to their excellent mechanical properties. In automobile industries the LM 25 aluminium is used in manufacturing of alloy wheels, connecting rod, engine blocks, and engine heads etc. In LM25 if they are reinforced with Silicon carbide and Activated Carbon, their total weight can be reduced and mechanical properties can be improved. In this sense we have selected the LM 25 Al alloy is used as a matrix material, Silicon carbide and Activated Carbon as reinforcements. The mechanical test results revealed that the LM 25 MMC’s have excellent wear resistance. The composite has been produced by Liquid metallurgy technique (stir casting). The properties of chosen composite is compared with base metal for Tension, Compression, wear and Hardness. This paper is aimed at development of aluminium metal matrix composites with hybrid reinforcement. Here aluminium alloy (LM25) has been selected as base metal along with silicon carbide various weight ratio and 2% activated carbon (AC) have been taken as reinforcements to produce hybrid composite.

Keywords: Aluminium alloy LM25, Stir casting, Microstructure, Hardness, Wear

I. INTRODUCTION

A new class of materials called ‘Composite materials’ has answered to this search to a great extent. Composite materials are created artificially by combining two or more materials which usually have dissimilar characteristics. The constituents of a composite material can be generally identified macroscopically. This is in contrast to usual metallic alloys whose phases can be identified only under higher magnification or microscopic examination. Composite materials are new generation materials produced to meet the demands of automobile and aircraft industries.
