摘要
研究了稀土变质对３０ＣｒＭｎＭｏ马氏体铸钢韧性的影响。添加稀土会使钢从室温到－６０℃时的韧性增加，其主要原因是细化了钢的组织，改善了马氏体亚结构，增加了残余奥氏体量及回火碳化物的数量并改善了其分布。
The effect of Rare Earth(RE) metamorphism on the cast steel 30 CrMnMo toughness is studied. RE Addition to increase the steel toughness (aku) at room temperature to minus 60℃ to mainly for refining the structure, improving submicrostructrue of martensites, raising residual austenites, increasing quantity of the tempered carbides and improving its distribution.
