高碳耐磨锰钢中的针、网状碳化物经Mg系变质剂变质处理后,在铸态下转变成团球状,且大量弥散地分布于奥氏体中。冲击韧性得到显著的提高,硬度也稍有提高。使该钢种不经热处理即可铸态使用,同时耐磨性得到显著提高。

The needle-like and network carbides in as-cast high carbon wear-resistant manganese steels will be nodularized and dispersed,by a large majority,in austenite aider modifying treatment with Mg system agents.The impact toughness of the steels is significantly improved and the hardness is also increased to a certain extent.As a result,the steels can be used in as-casted state without any heat treatment and their wear resistance can be greatly enhanced.
