摘要
通过化学成分的优化，Ｎ、Ｃｒ等元素的加入和变质处理等措施，得到在稳定性较低的奥氏体基体上弥散分布有粒状碳化物的铸态组织。这种铸态锰钢具有初始硬度高、韧性好、加工硬化能力强和抗磨性高等特点。并重点分析了铸态锰钢的抗磨机理。
By means of optimum chemical compositions, additions of N, Cr into the melt and modification procedure, an as-cast structure with metastable austenite matrix and relatively even distribution of carbide particles was obtained. And so, an as-cast manganese steel, which has higher initial hardness, good impact toughness, better work-hardening ability and wear resistance, has been developed. The mechanism of wear resistance of the as-cast manganese steel was mainly analyzed.
