Effect of Excess Mg on the Microstructure and Mechanical Properties of Al-Mg₂Si High Pressure Die Casting Alloys

Abstract:

In this work we found that the addition of excess Mg can significantly improve the mechanical properties of pseudo-binary Al-Mg₂Si alloys after high pressure die casting (HPDC). Al-8Mg₂Si-6Mg alloy offered an excellent combination of high strength and reasonable ductility. Excess Mg lowers the Mg₂Si content in the eutectic reaction and promotes the formation of Mg₂Si as the primary phase, and this is believed to be the origin of improved mechanical performance.
