研究了铈在低碳粒状贝氏体钢中的合金化作用。结果表明，铈能增大粒状贝氏体相变的孕育期；影响粒贝相变的形核和长大方式；细化空冷粒贝组织。
The alloying effect of cerium in low-carbon granular bainitic steel was studied. The results showed that cerium can increase the gestation period of granular bainite transformation, influence the nucleation and growth pattern of the grain-shell transformation, and refine the air-cooled shellfish.
