Abstract

The recent research investigates on A356 aluminium alloy reinforced with Multi-Walled Carbon Nanotubes (MWCNTs) prepared through permanent mould casting for feedstock preparation and thixoforming in a hydraulic cylinder press to form Metal Matrix Composites (MMC). The impact of T6and T5heat treatment on thixoformed aluminum A356 reinforced with MWCNTs is explored in this study. The reinforcement (MWCNTs) content is 0.5wt% and 1.0wt%, respectively, and the wetting agent (Magnesium flakes) which helps to bind together is 0.5wt% and 1.0wt%. To uniformly disperse CNT in Al, the composition of the metal matrix and reinforcement is blended either about 10minutes or 15 minutes by a mechanical stirrer of the turbine type. Following the thixoforming procedure, the sample will be microstructural analysed before being subjected to T5 heat treatment. The T5 heat treatment consist of an artificial ageing process in which the alloy will be heated to 200 °C for 4 hours to allow precipitation to occur. The microstructure of each specimen was studied using scanning electron microscopy (SEM) and X-ray diffraction (XRD) to determine the phase of enhanced microstructure arrangement. Then a micro pod tribo tester is utilized to analyse on the wear performance of the tested specimen.
