Characterization of functionally graded Al-SiC p metal matrix composites manufactured by centrifugal casting

Casting of SiC Reinforced Metal Matrix Composites

Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...

Semisolid Processing of Al/β-SiC Composites by Mechanical Stirring Casting and High Pressure Die Casting

Machinability behavior of PCD 1600 Grade Inserts on Turning AL/SiC/B4C Hybrid Metal Matrix Composites

Aluminium metal matrix composites reinforced with SiC and B4C particles are a unique class of advanced engineered materials that have been developed to use in high strength , high wear resistant and tribological applications. The conventional techniques of producing these composites have some drawbacks. In this study, the aluminium hybrid composite is fabricated using stir casting method. 10 % ...

Compoforging of Al-Si Metal Matrix Composites Reinforced with -SiC: An Alternative Technique

This paper reports the -SiC particles surface modification by copper Electroless Plating (EP), as well as a morphological characterization of Al-Si reinforced composite obtained with such modified particles and consolidated by compoforging. The -SiC particles were obtained by thermal degradation of organic waste. The compoforging technique is a hybrid between the compocasting process and semi-s...
