Aluminium powder metallurgy

Abstract

Conventional press and sinter aluminium powder metallurgy is a well-developed, cost-effective process for net-shaped fabrication of complex parts via die compaction and sintering. This chapter provides an overview of the PM process in general and sintering in particular. Key issues in the PM processing of aluminium are considered, including the roles of magnesium and the atmosphere on sintering and how these factors affect densification and the microstructure.
