Powder metallurgy processing of aluminum alloy based metal matrix composites (MMC) is realized to be a promising alternative as expected to advance rapidly compared to other conventional methods. This paper reviews the extensive development in metal-matrix composite research works with particular focus on aluminum alloys 2xxx series as metal-matrix particulates processed by powder metallurgy route. Effect of reinforcement materials such as SiC and Al2O3 on the mechanical properties of the composites manufactured through conventional methods and powder metallurgy route are compared and presented. The influence of percentage of reinforcement material on the overall properties of the MMC’s as reported by the researchers are presented. Summary on fundamental aspects of manufacturing MMC’s via powder metallurgy route, the effect of mechanical properties, tribological properties, and microstructural properties are presented. Eventually, some advantages of powder metallurgy method are mentioned which may substantiate the claim to consider this as a novel method for near net shape manufacturing.

Graphene being one of the allotropes of carbon, has attracted and evoked keen interest in recent times as an ideal reinforcement for the composites due its outstanding strength. In the current research work, the fatigue and wear behavior of Al6061âGraphene (varying weight fraction 0.2, 0.4, 0.6Â&nbsp;wt%) particulate composite are investigated in comparison with monolithic alloy. Initially dispersion of Graphene is carried out by ultra-sonication followed by ball milling on adding Al6061 alloy powder, consolidated by powder metallurgy process and subjected to sintering under inert gas atmosphere. The investigation on the effect of Graphene flakes on micro hardness, mass loss, coefficient of friction and surface roughness values are done under different loading conditions for the prepared samples and wear tracks are analyzed under a microscope. The possible reasons for crack initiation and subsequent fatigue failure under cyclic loading with stress ratio RÂ&nbsp;=Â&nbsp;â1(sinusoidal waveform), cyclic frequency 5Â&nbsp;Hz and stress amplitude 40â140Â&nbsp;MPa at room temperature conditions and the type of wear due to increase in Graphene weight fractions were studied through tests results and SEM characterizations.
