Microstructure and Properties of Mg-Al Based Casting Alloys Modified with Minor Alloying Elements

Abstract:

Article Preview

Minor alloying elements such as RE, Sb, and Si were added to Mg-Al based commercial alloys and their effects on the mechanical properties, corrosion resistance, and castability were investigated.The result show that small amount of cerium-rich misch metal (RE) addition with antimony enhances the heat resistance of AZ91 alloy effectively without deteriorating other good properties. The addition of Si with RE was also found to improve the heat resistance and casting capabilities (fluidity and hot cracking resistance) of AM50 alloy.
