| Abstract | ||
| This research aimed to prepareAl-12Si alloys by powder metallurgy method because of its commercial and technological importance. Aluminum and Silicon powders were used, then mixed and blended together and classified into four parts, carbon powder was added to the three parts (5,10 and 15% wt) and the last remain as it is. These powders were mixed to ensure a good distribution of Zinc powder, and then they compacted in is ostatic cold pressure at 10 ton, the compact samples were sintered in furnace under argon gas at 530°C for one hour, These samples were then prepared (grinded, polished and etched) for them icrostructure examination, density, porosity, microhardness, X-ray diffraction and wear resistance. The results showed anincrease in the density and the hardness with addition ratio. | ||
