| Abstract: | The development of high strength low alloy (HSLA ) steel plate is reviewed in this paper, and comments on several typical HSLA st eels are presented. Based on rolling process and theories of duplex microstruct ure strengthening and toughening, a new microstructure design for high strength steel plate—grain boundary allotriomorphic ferrite/granular bainite (FGAB /BG) duplex microstructure is proposed. |
