Die soldering is one of the main issues limiting the productivity of Al die castings. Soldering is explained as a phenomenon in which Al melt welds to the die surface. It can occur due to the interface reaction between the Al alloy melt and die. The interfacial reaction between tool steel and liquid Al causes formation of intermetallic compounds between Fe and Al. The interaction of tool steel with liquid Al has been mainly studied on typical Al casting alloys such as A380, which contain low Mg content. Increase of Mg amount in Al alloy provides improvement of strength and corrosion resistance as well as weight reduction. Our study has been mainly focused on new Al casting alloy development with high Mg content (5-10mass%). The aim of this study is to investigate effect of Mg amount on interface reaction between molten Al alloy and tool steel.
