AI Technical Summary

Technical Problem

The existing high-manganese steel has low initial strength and hardness, which makes it easy to deform and has insufficient wear resistance in the early stages of use. Existing alloying and heat treatment methods have limitations in improving strength and toughness.

Method used

The heat treatment process of Cr-Mo-V alloyed high manganese steel is adopted. Through rapid heating and cooling technology, an austenitic structure with differences in alloy composition at the submicron scale is obtained in the high manganese steel, avoiding the harmful structure caused by the segregation of alloying elements and improving the strength and plasticity of the material.

Benefits of technology

It significantly improves the yield strength, tensile strength and elongation of alloyed high-manganese steel, enhances the wear resistance of the material, and reduces the material cost.
