A hybrid-hybrid (ultrasonic-assisted + laser-assisted) turning study of silicon carbide reinforced aluminium metal matrix composite is presented. The results show a significant reduction average cutting force with an improved surface finish machined components compared to conventional machining, implying that this new and novel paradigm viable machining process.

The main objective of this investigation is to study the microstructural features and evaluate tensile strength, hardness, acidic corrosion resistance liquid metal stir casted aluminium-silicon carbide (Al-SiC) composite. As reinforcement for Al alloy matrix, SiC particles were added matrix in percentages 0%, 10%, 20%. microstructure Al-SiC composite was studied using optical microscope. effect...

PURPOSE Aerosol deposition is a technology for coating ceramics with impact consolidation at room temperature. The aim of the present study was to investigate the thickness and the microstructure of the aluminium oxide layer on different three dental resin composite materials created by means of aerosol deposition. METHODS Disk-shaped specimens were fabricated with three resin composites (Est...

The tensile properties of an aluminium-based metal matrix composite reinforced with a-alumina platelets were investigated from an experimental and a theoretical point of view. An increase in Young modulus, 0,2% proof stress, flow stress and ultimate tensile strength was observed over the unreinforced metal. These improvements were obtained at the expense of the tensile ductility. The experiment...

The present requirement of automobile industry is seeking lightweight material that satisfices the technical and technological requirements with better mechanical and tribological characteristics.  Aluminium matrix composite ( AMC ) materials meet the requirements of the modern demands. AMCs are used in automotive applications as engine cylinders, pistons, disc and drum brakes. This paper inves...

functionally graded aluminium/zirconia metal matrix composite was fabricated using stir casting technique followed by horizontal centrifugal casting process and a hollow cylindrical functionally graded composite (150 x 150 x 16 mm) was obtained with centrifuging speed of 1200 rpm. the microstructural evaluation and hardness test was carried out on the outer and inner surface of the functionally...

The current research compares the processing influence of Spark plasma sintering (SPS) over conventional sintering on aluminium alloy AA2219 MWCNT composites. Also investigations on the effect of MWCNT content on the properties of composite are presented and discussed. Though unreinforced matrix processed under SPS showed 24.68% improvement in hardness over conventional, the same could not be r...

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 % ...
