Steel GX120Mn12 Modifying by Ultra Disperse Powders of Refractory Metal Oxides

Abstract:

The article provides a consideration of the technology of producing steel GX120Mn12 with high manganese content modified by the special modifier to improve constructional durability of details manufactured. The ultra disperse powder of refractory metal oxides was used to carry out the process of modifying. The samples were produced in the series of cast and tested mechanically. Structural research demonstrated improvement of steel microstructure and that of its mechanical characteristics. It also revealed that the size of austenite grain and nonmetallic inclusions on borders of grains were reduced, and sulphide inclusions were dissolved partially. It has positive impact on work characteristics of this steel.
