High strength low alloys (HSLA) steels with excellent high strength, high toughness, good corrosion resistance and weldability, can be widely used in shipbuilding, automobile, construction, bridging industry, etc. The microstructure evolution and then mechanical properties can be influenced by thermomechanical processing. In this study, themomechanical processing is optimized to simultaneously control the matrix microstructure and nano-scale precipitates in the matrix. It is found that the low-temperature toughness and ductility of the steels are significantly depend on the matrix microstructure during enhancing the strength by introducing the nano-scale precipitates. The effects of alloying elements on the microstructure evolution and nano-scale precipitation are also discussed.
