摘要
在３０ＣｒＭｎＳｌＡ钢中加入了不同量的砷（Ａｓ）和锑（Ｓｂ），应用扫描电镜、透射电镜及俄歇能谱研究了这些元素对低温回火脆性的影响规律。结果表明该钢的低温回火脆性是马氏体条间碳化物析出而产生准解理断裂所致，杂质元素的存在则会增加脆性的程度，且Ｓｂ的作用明显强于Ａｓ的作用。
The different quantities of As and Sb were added to 30CrMnSiA steel,The influencing regulaties of these elementson temper martensite embrittlement were investigated by TEM,SEM and ABS.The results show that temper martensite embrittlement is correlated with interlace carbides whic h initiated quasl-cleavagefracture. Impurity elemcnts may incrcase extent of embrittlementand effect of Sb is stronger than As.
