The general situation of research and development of ultrafine grain steel in China and other countries was introduced. Various methods of grain refinement were expounded, and the large plastic deformation of which was mainly expounded. And the problems in it were put forward. Comprehensive application cases and research results of different plastic deformation method were provided. From the actual start, the production of ultrafine grain steel was expected combining with the research situation in China and other countries.
