Bismuth Effect on the Mechanical Properties of Antifriction Al-Sn Alloys


Al-Sn alloys were produced by the induction melting method with different Bi additions. Microstructure shows grains 130 μm average size. Fracture toughness and hardness tests have shown that ternary alloying elements present significantly affected the samples with Bi alloying. Plastic deformation was evaluated by using the forging test; the results have shown that the addition of 3.5 at.% Bi increased the value at least twice as compared with unalloyed sample. Wear test indicated that bismuth slightly affected the tribological behavior. It was found that a concentration of 3.0 at.% Bi, considerably enhances the alloys performance.
