| Abstract: | 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. |
