Al-Si Alloys

Abstract

This chapter deals with the production of Al-Si alloys by powder metallurgy as well as the physical and mechanical properties developed by this processing method as compared to others. The main focus is Al-Si hypereutectic alloys, using the 393 alloy as a benchmark. The sintering process and the effects of grain refinement are covered as well as the manufacturability of the samples for high quality and high complexity, and in general are ideal for neat net-shaped parts. The chapter concludes by comparing products of powder metallurgy and conventional casting with a brief explanation on developing superior mechanical properties.
