| Summary: | Title screen The effect of copper additions up to 2 wt % on the structure and mechanical properties of sintered and deformed Al-20Sn composite materials (CM) was studied. The investigated samples were obtained by the vacuum sintering of compacts made of a mixture of pure metal powders. Equal channel angular pressing by route A (ECAP (A)) was chosen as the method of deformation. It was founded that copper is located mainly as brittle inclusions in Sn interlayers and only a small part of Cu dissolves in the aluminum matrix. The strength and hardness of sintered CM are increased with the increase of Cu content and intensity of deformation, but the CM ductility is significantly reduced. The low ductility of the deformed Al-20Sn-Cu CM leads to their catastrophic wear under the dry friction against steel disc. |
