Exploring the concept of castability in magnesium die-casting alloys

摘要

This paper provides a summary of the recent work completed and history of the measure of manufacturability in the magnesium diecasting industry.The most popular die-casting alloys utilized in this industry are based on the Mg-Al system,including AZ91,AM60 and AM50.These are well-established alloys,and are generally considered to be highly castable.However,the concept of castability in magnesium die-casting is not a well-defined characteristic or quantitative material property.As a result,the author investigates the subject of castability for magnesium die-cast alloys and how it relates to the development of alloys for innovative applications or improved properties.This paper provides a summary of some key findings in literature on the castability of magnesium die-cast alloys,how castability is defined and evaluated,the impact of different alloying elements on the castability of magnesium alloys,and suggestions for future work.©2020 Published by Elsevier B.V.on behalf of Chongqing University.
