Modified Al alloys are gaining emphasis in the past few years due to wide range of properties available for the engineering applications. These alloys are manufactured by spray forming process have superior properties over the conventional cast alloys. Hence in this article an attempt has been made to summarize the work that has been carried out in the field of spray forming of hypereutectic Al – Si alloys and with other alloying elements such as Fe, Cu, Mg and Mn. As hypereutectic Al – Si alloys are attractive for the industrial applications due to their low thermal expansion co – efficient and high tribological properties. In this study attention has been paid towards the microstructure, mechanical and tribological properties of the studied alloys. The study of process parameters over the size and shape of the powder in spray forming is other part of this work. The change in properties of spray formed alloys by the working of secondary process is also been considered.
