Description
Technical Field
The invention particularly relates to high manganese steel, and particularly relates to austenitic high manganese steel and a preparation method thereof.
Background
The main chemical components of the standard austenitic high manganese steel are carbon and manganese, a single austenitic structure can be obtained after water toughening treatment, and the work hardening mechanism of the high manganese steel has two theories of dislocation accumulation and deformation induction transformation. More recent research has supported the dislocation pile-up theory. It is considered that the high manganese steel is highly strengthened by friction due to the formation of a large amount of dislocations, twinning deformation, silver intercalation defects, and blocky structure refinement. When the dislocation density reaches a limit value, slip is virtually impossible, which is the predominant form of deformation for twinning.
Although there are many new materials to partially replace high manganese steel in recent years, the high manganese steel has been improved from various aspects and has been greatly exchanged. The method mainly comprises three approaches, namely re-alloying of high manganese steel, changing the Mn/C ratio of the high manganese steel and improving the production process, wherein various alloying or micro-alloying methods are widely used at home and abroad for improving the performances of the wear resistance, the yield strength and the like of a plurality of austenitic high manganese steels on the market at present, or various alloying or micro-alloying methods are widely used at home and abroad for improving the wear resistance and the carbon content, but the influence on the wear resistance is not obvious when the carbon content exceeds 1.5 percent, and the impact toughness of the material can be obviously reduced when the carbon content is improved while the wear resistance of the high manganese steel is improved, wherein the alloy elements such as alloy elements for improving the yield strength and the tensile strength are V Mo Cr in turn, but V, Mo and Cr all reduce the elongation and the impact toughness, for example, 2 percent of Cr is added into Mn13, namely Mn13Cr2, can improve the yield strength and improve the wear resistance, but the precipitation tendency of grain boundary carbides is increased, thereby reducing the ductility sum of the steel by 30-40% compared with Mn 13.
Therefore, in summary, although the re-alloying method can improve the yield strength and wear resistance of the high manganese steel, it will cause the elongation and impact toughness to decrease, and it is easy to increase the carbon content to improve the wear resistance and also to decrease the hard gas impact toughness.
