Characteristics study on aluminium graphene composite for different sintering approaches

Abstract

Aluminium alloys and its composites are the most important engineering materials, which have been broadly utilized in Automobile and Aviation industries due to its properties like low density and good structural rigidity. Graphene is having the allotropes of carbon which are used as filler and perfect reinforcement for traditional materials used for structural applications.. This research is carried out to analyse the Al 6061 matrix micro composites with different reinforcement content of Graphene (0.25, 0.50, 0.80 weight %). The Ball M illing process is carried out to achieve uniform dispersion of the graphene and the mixtures were prepared by powder metallurgy (PM ). The prepared compacts are sintered by using the box furnace and microwave sintering. Hardness and green density are investigated for different types of sintering and Graphene weight fraction. Experimental results will give the dimension for the preparation of Al – Graphene composites considering the hardness and green density.
