Abstract

Researches have shown that the mechanical properties of bearing alloy depend to a large extent on its microstructure and the morphology and quantity of each constituent phase. In order to study the effects of microstructure on mechanical properties of tin-based bearing alloy, the finite element simulation based on actual microstructure was employed to reveal the influence rules. The results show that the composition, size, content and morphology of hard phases have an important influence on the mechanical properties of tin-based bearing alloy. The fine and uniformly distributed hard phases can make the stress distribution in the alloy more uniform under external load and can effectively reduce the stress concentration. It is recommended to refine the grains of hard phases and make them uniformly distributed to obtain the high-performance tin-based bearing alloy. In addition, the diagonal size of SnSb phase should be less than 150 μm, and the content should preferably be controlled below 15%. It is hoped that this paper could provide the theoretical guidance and reference to the micro-design of tin-based bearing alloy.
