摘要
研究了铸造复合中锰奥氏体钢在冲击磨料磨损条件下的耐磨性能。结果表明：铸造复合中锰奥氏体钢的耐磨性是高锰钢的５．４１倍。复合层中碳化物结构为（Ｃｒ，Ｆｅ）２３Ｃ６和（Ｃｒ，Ｆｅ）７Ｃ３，呈网状分布，具有抑制磨粒压入基体和阻碍磨粒对基体的切削作用。亚表层中介稳奥氏体发生应变诱发马氏体相变，转变能来源于外界冲击功，其值为４３４Ｊ·ｍｏｌ－１。
The wear resistance of casting composite medium manganese steel has been studied under the condition of impact abrasive wear. The results show that the wear resistance of casting composite medium manganese steel is 5.41 times that of Hadfield steel.The structures of carbides in composite layer are (Cr,Fe)23C6 and (Cr,Fe)7C3, and they distribute as net. The carbides had the effects that they hinder pressing and cutting to matrix.The strain induced martensite took place at subsurface.The energy of martensite tranformation comes from impact energy, value of which is 434J·mo1 -1 .
