High manganese steel releases manganese gas during smelting. The study used a thermal analyzer to show that manganese evaporation increases with temperature and time. Manganese volatilization follows a specific model, with manganese oxides being the main volatile products. The process involves manganese atoms forming oxides on the steel surface and evaporating, or vaporizing into manganese vapor and then oxidizing. The research found that the first form is the main way manganese evaporates in high manganese steel.
