Further refinement of grains as well as the decrement and refinement of bainite and martensite, hence, a mixed structure of equiaxial and acicular ferrite in the steel may be achieved by RE addition. The ultrairdcrostructural RE inclusion, which is able to contribute RE-containing steel for refinement of grains in the process of controlled rolling, is observed on the fracture surface. Therefore, a satisfactory combination of mechanical properties, such as improved strength and impact toughness, may be approached for the steel containing RE addi(?)ion. 收稿日期: 1987-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 蒋景凯 肖连芳 尤德林 束家生 任立娥 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/165 1 福田実,橋本保,国重和俊.鉄鋼,1972;58:1832 2 #12 3 #12 4 Mclean D, Northcott L.
