氮、碳、锰对介稳奥氏体锰钢力学性能及耐磨性的影响

 研究了氮、碳、锰等合金元素对介稳奥氏体锰钢力学性能及耐磨性的影响。结果表明，在中、小冲击磨损工况条件下，由于应力波效应，决定锰钢耐磨性的因素有2个：加工硬化性和机械强度，而且2个因素相互制约，只有当这2个因素的提高幅度都较大时，其耐磨性才能大幅度提高。将15C 127Mn奥氏体锰钢的碳的质量分数大约降至1%，锰的质量分数降至≤8%，同时加入质量分数约01%的氮时，可得到一种新型耐磨材料——氮微合金化介稳奥氏体锰钢。

Effect of Nitrogen, Manganese and Carbon on Wear Resistance and Mechanical Properties of Metastable Austenitic Manganese Steel

The effect of nitrogen, carbon and manganese on mechanical properties and work hardening ability metastable austenitic manganese steel was studied. The results indicated, in impact working condition, because of effects of stress wave, the wear resistance can be improved greatly when the work hardening capacity and mechanical properties are increased together significantly. For 15C 127Mn austenitic manganese steel, when the carbon content is decreased to about 1%, the manganese content and nitrogen content are ≤08% and ≈01% respectively, a new wear resistant steel (nitrogen microalloyed metastable austenitic Mn steel) can be obtained.
