摘要
用电子探针分析了稀土在5crMnMo钢中的分布,研究了不同稀土含量对奥氏体晶粒度的影响,实施结果表明,稀土分布于奥氏体晶界,使5CrMnMo钢的奥氏体晶粒度显著细化。
In this paper,the distribution of RE in the steel 5CrMnMo is investigatied with EP-M A and the effect of various RE contents on the grain size of austenite of the steel is studied ,the results show that the grain size of austenite refined significantly due to the RE distributed in the crystal baundary of austenite.
