Aluminum matrix composites reinforced by ceramic particles are well know for their good thermo-physical and mechanical properties. As a result, during the last years, there has been a considerable interest in using aluminum metal matrix composites (MMCs) in the automobile industry. These potential applications have greatly stimulated the tribological studies of MMCs under different operating conditions. In this paper, TiB – particles - reinforced aluminum - tungsten matrix composites were fabricated by the cost – effective squeeze – casting technology and their microstructure characteristics and mechanical properties were investigated. The microstructure observation showed that the produced composites were dense, with no micro-holes and obvious defects. Their wear resistance was evaluated using a pin on disc type equipment under dry wear conditions and found significantly increased compared to pure Al metal.


The present investigation centers at assessing the mechanical properties of Aluminum within the sight of Silicon di-oxide, and their blends. The creations were signified the necessary level and mix throwing technique was utilized for the improvement of Aluminum Metal Matrix Composites. Basic portrayals were done on Metal Matrix Composites by X-beam diffraction techniques and Field Emission Scanning Electron Microscopy (FE-SEM) was utilized for the miniaturized scale basic examinations. The tests for mechanical properties of metal lattice composites like tensile quality and Hardness were done. Within the sight of Silicon di-oxide (0-10%) with Aluminum grid, it was clear that the densities of the composites were diminished and the hardness was expanded. Correspondingly, a decline in rigidity additionally had been seen with decline in support in the Metal Matrix. The SEM examination completed for contemplating the Material Morphology has likewise been emerged in this investigation
