Development of Aluminium based Bearing Alloys

Abstract

In order to develop a good bearing alloy for structural applications in industries, the present work was planned. Before testing the mechanical properties including bearing property it is essential to nderstand their structural features as structure is going to govern the property. Considering this aspect the proposal was planned. The thesis describes about the different bearing alloys used in industry, their properties and limitations. In order to overcome these limitations, some idea was planned and accordingly experiments were designed and performed. Among the end application, one of the applications is piston alloys where distribution of silicon phase is considered to be important to achieve good mechanical strength alongwise good wearing property. Considering this fact alloys of near eutectic composition (hyperside) were made. In order to understand the distribution of silicon phase different alloying elements were added. These influence the development of varieties of structure. The present work emphasizes on the structural features of these alloys.
