PRODUCTION, MICROSTRUCTURE AND MICROHARDNESS OF ALUMINUM-MATRIX COMPOSITES ALLOYED WITH CARBON

Investigation of Parameters Involved in the Production of Aluminum Matrix Composites Using Hot Powder Extrusion

Aluminum matrix composites reinforced with Al2O3 and SiC particles (5 Vol%) were produced using the hot powder extrusion method. Extrusion temperature and extrusion reduction in area were chosen in the range of 500 to 600°C and 90 to 95%, respectively. The physical and mechanical properties of the extruded composites such as density, tensile strength, elongation and microhardness were evaluated...

Mechanical and Tribological Behavior of Aluminum Alloy LM13 Reinforced with Titanium Dioxide Metal Matrix Composites

In the present research work physical, mechanical and tribological behavior of Aluminum (Al) alloy LM13 reinforced with Nano-sized Titanium Dioxide (TiO2) particulates were fabricated, mechanical and tribological properties were investigated. The amount of nano TiO2 particulates in the composite was added from 0.5% to 2% in 0.5 weight percent (wt %) increments. The Al-LM13-TiO2 Metal Matrix Com...
