【摘要】 根据Ｍｓ点温度设计锰、碳成分，得到中锰奥氏体钢，通过水韧处理和回火，使工件达到硬度和韧性的最佳配合，并在随后的冲击磨损工作条件下，表面形成大量的形变α马氏体或ε马氏体，达到耐磨要求。根据试验结果，所研究的中锰钢有良好的效果，能满足使用要求。更多还原

【Abstract】 According to the temperature Ms,the content of manganese and carbon is designed for medium manganese steel The new steel has an optimum coupling of strength with toughness Treated by water soluting and tempering,a large amount of deformed α or ε martensite are being formed during working at low impacting load.Its wear resistance is then fit for operating demand更多还原
