Influence of interfacial segregation of Sn microalloying on internal oxidation of Fe–Mn–Si based alloys

Key Points

• Internal oxidation is significantly influenced by interfacial segregation of Sn microalloying.
• Observations indicate that higher Sn content leads to increased oxidation resistance in these alloys.
• Analysis of oxidation mechanisms reveals specific interactions at the alloy interfaces.
• Findings suggest that microalloying with Sn could optimize the properties of Fe–Mn–Si based alloys.
