Summary

The past decade has witnessed significant growth in the utilisation of magnesium alloys. This has been primarily driven by the concerted efforts of automotive manufacturers to reduce the weight of vehicles in order to meet stringent fuel economy standards. The most efficient method for the manufacture of magnesium parts is via high pressure die casting. It is a productive and cost-effective process for light metals that is capable of high surface quality and dimensional accuracy. Although die casting is an established process, the relationships that exist between the processing, microstructure and properties are inadequately understood. The present study identified process-microstructure-property relationships for three Mg-Al alloys (AZ91D, AM60B and AS21) through the development of a diverse range of microstructures via the manipulation of four processing variables, and the correlation of these resultant structures to the tensile properties. The processing variables investigated were gate velocity (Vgate), accumulator pressure (Pacc), die (Tdie) and casting temperatures (Tcast).
