摘　　要：简要论述了超细晶粒钢的几种主要生产工艺以及国内外超细晶粒钢研究的发展情况。通过对各工艺的优缺点进行分析比较,认为将奥氏体晶粒超细化和后期相变控制有效结合起来的超细晶生产工艺具有良好效果。Several kinds of key technologies for manufacturing an ultra-fine grained steel are briefly discussed. Developments on technologies for manufacturing the uhra-fine grained steel at home and abroad are introduced. Based on analysis on merits and drawbacks of these technologies by comparison, it is believed that good results can be achieved in manufacturing the ultra-fine grained steel by using the technology with refining austenitic grains combining efficiently with controlling the phase transformation at later stage.
