Abstract: The present work explores the microstructural and mechanical properties of Aluminium (Al) Metal Matrix Composites (MMCs) fortified with Zirconium Oxide (ZrO2) and nanographene particles. The composite material is processed by the mix fluid metallurgy course. ZrO2 and graphene is blended in various extents in which ZrO2 (1 wt. %) reinforcement is kept steady and graphene support is varied independently with 0.5 and 0.75 wt. %. Utilizing optical and SEM equipment, micro examination is conveyed and results uncover that uniform circulation of ceramic zirconium dioxide (ZrO2) and graphene particles are found in the as cast Al6061 MMCs. Fourier-Transform Infrared Spectroscopy (FTIR) investigation is done to know the quality and measure of fortification present in composites and notes the energy gap (Eg) obtained as 4.05 eV. Mechanical tests according to ASTM standards were led on the composites viz., tensile strength, yield strength and % elongation to check the properties of Al based MMCs. The consequence of this work is reasoned with a noteworthy improvement in tensile and yield strength values of the processed composites however, the percentage elongation diminishes with the addition of reinforcement content in the fabricated composite.

TL;DR: In this article, the composites of graphene platelets and powdered aluminum were made using ball milling, hot isostatic pressing and extrusion and the mechanical properties and microstructure were studied using hardness and tensile tests, as well as electron microscopy, X-ray diffraction and differential scanning calorimetry.
Abstract: Composites of graphene platelets and powdered aluminum were made using ball milling, hot isostatic pressing and extrusion. The mechanical properties and microstructure were studied using hardness and tensile tests, as well as electron microscopy, X-ray diffraction and differential scanning calorimetry. Compared to the pure aluminum and multi-walled carbon nanotube composites, the graphene–aluminum composite showed decreased strength and hardness. This is explained in the context of enhanced aluminum carbide formation with the graphene filler.

TL;DR: In this paper, a 1.0-wt.% graphene reinforced aluminum 6061 (Al6061) composite was synthesized to investigate the effects of graphene dispersion by ball milling technique.
Abstract: A 1.0 wt.% graphene reinforced aluminum 6061 (Al6061) composite was synthesized to investigate the effects of graphene dispersion by ball milling technique. The Al6061 powder and graphene were ball milled at different milling times. The composites were then synthesized by hot compaction in the semi-solid regime of the Al6061. A three point bending test was performed to characterize the mechanical properties of the composite. The ball milled powder and the fracture surfaces of the composites were analyzed using the scanning electron microscopy. A maximum enhancement of 47% in flexural strength was observed when compared with the reference Al6061 processed at the same condition.
