摘要
利用俄歇能谱(AES)分析技术,对钢轨钢的界面(解理面、晶界面)进行成分分析。实验结果表明,钢轨钢中加入稀土元素后,界面上的P、S原子偏聚基本消失,使界面得到明显的净化。
The composition analyses on the interface (such as cleavage facet or grain boundary) in the rail steel have been carried out by AES technique. The experimental results indicate that the Rare Earths can inhibit the segregation o the impurity elements such as P and S on the interface and play an important role for purifying the interface of the rail steel.
