Procedia Manufacturing

Aerospace and automotive industries are eager on introducing hybrid metal matrix composites in their components due to their excellent mechanical and physical properties, leading to reduction in the weight of structural components and energy requirement for propelling. Components made by hybrid metal matrix composite (based on Aluminum alloy reinforced with single wall and multi wall carbon nanotubes, Graphene and ceramic particles) required secondary operations to enhance the dimensional tolerance and surface finish. Machining operations generally requires minimum tool wear rate and good surface finish with lowest energy requirement. Hard metal, ceramic and oxide reinforcements in the composite increase the tool wear and machining cost. To improve tool life and increase the metal removal rate significant care is needed for the selection of optimum cutting parameters and cutting conditions. This review focuses on the influence of reinforcement particle's types, shape, size and volume fractions on the machinability issues like the cutting force, tool wear, chip formation and surface roughness. Further, the role of various cutting parameters like cutting speed, feed, depth of cut and tool material, tool geometry and cutting conditions during turning of hybrid metal matrix composites are critically reviewed.

Machinability of Hybrid Metal Matrix Composite - A Review

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.
