Experimental and simulation analysis of the tensile properties of aluminium alloy hybrid composites reinforced with graphite and boron carbide

Abstract

In recent years Metal Matrix Composites (MMCs) have attracted much attention due to their excellent mechanical properties such as high specific strength and wear resistance. Some of the typical applications are bearings, automobile pistons, cylinder liners, piston rings, connecting rods, sliding electrical contacts, turbocharger impellers, and space structures. MMCs components need to be formed into the desiderate shapes and finished to the required dimensions and tolerances. In the present work, a brave is consummate to prepare and compare the tensile properties of LM25-Gr and LM25-graphite/boron carbide (B₄C) hybrid composites. The composites were primed to make use of stir casting process in which the quantity of reinforcement is speckled from 4 wt% of Gr and 3wt% of B₄C. The prepared composites are tensile properties were estimated as per the standards. Finite element method was employed in this work. Experimental results were in good agreement with numerical results.
