The work presented in this paper examines additions of titanium and magnesium on their own and together in 1030. Mechanical testing, thermal analysis, and metallography were conducted on the heats. Additions of both magnesium and titanium produced the highest mechanical properties. The solidification structure was refined by all additions. Thermal analysis determined that magnesium increased the solidus.
 
Inclusion analysis found TiN formed in all heats containing titanium. The TiN particles initiated on complex magnesium-aluminum oxides. There is strong evidence that the magnesium additions form oxides that assist the formation of TiN, which then assists the formation of δ-ferrite during freezing, with the final result being better properties.
