The 200g of surface polished manganese steel (about 5% manganese content) and 50g of prepared slag powder was put into MgO crucibles and kept for 100 min at 1600°C with high purity argon protective atmosphere to ensure complete steel/slag reaction. Subsequently, the steel and slag samples were quickly taken out of the furnace and quenched in water.
