| Abstract: | In this paper, carries out a stimulated experiment with controlled rolling and cooling for 14MnNbq steel plate. Using some analysis techniques and methods, such as optical microscope, transmission electron microscope, mechanical behavior experiment, we analyze the experimental results and prove that that 14MnNbq steel possesses high strength and toughness. It can meet technical requirements of steel used in heavy bridge. We also provide the primarily mechanism of strength and toughness of 14MnNbq steel. |
