Influence of Heat-Treatment on Mechanical Properties and Wear Resistance of Ultra-High Mn Steel

The influence of heat-treatment on mechanical properties and wear resistance of ultra-high Mn steel was studied, micro-structure and fracture surface were analyzed by optical microscope (OM) and selected electron microscope (SEM). According to the results, optimized heat-treatment makes improvement in mechanical properties, and dispersed tiny carbides precipitate on Austenite matrix instead of grain boundary contributes to the excellent mechanical properties and wear resistance.
