Abstract
This study focuses on the reinforcement of high-manganese steel castings through the
incorporation of magnesium, calcium, titanium, and other surface-active elements, with particular emphasis on
enhancing the integrity of ceramic–metal composite structures. The experimental results reveal that surface
modification of manganese steel with magnesium significantly improves interfacial adhesion between alumina
ceramics and the metallic matrix, which is associated with the formation of well-developed interfacial zones.
Furthermore, the composite framework formed at the interface between the modified molten manganese steel
and alumina contributes to improved wear resistance compared to conventional high-manganese steel. The
wear resistance was enhanced by a factor of seven relative to untreated Hadfield steel. In addition, the
characteristic strain hardening behavior of high-manganese steel was found to be notably altered under the
influence of the reinforced surface composite structure, suggesting new approaches for tailoring mechanical
performance under severe service conditions. These findings highlight the potential of surface modification
techniques in optimizing the durability and mechanical reliability of high-manganese steel castings.
