Abstract
The article describes the results of metallographic investigations of manganese steel before and after the furnace treatment, namely treatment by calcium strontium carbonate, purging with argon in the ladle and in their joint conduct. The quantitative analysis of non-metallic inclusions was made and the location of non-metallic inclusions on grain boundaries was studied. With the help of electronic microscope the authors studied in detail the composition and shape of the inclusions formed at ladle treatment and without it. The mechanism of formation of globular inclusions in steel during solidifi cation of the metal in ladle treatment is described. The effect of diff erent types of ladle treatment on indicators of impact strength of manganese steel was considered, as well as the process of vanadium alloying of manganese steel. The paper presents practical data on the eff ect of vanadium alloying of manganese steel at a level of toughness.
