摘要： The present invention relates to a method of manufacturing bulk nano-structured low carbon steel, comprising the steps of: preparing a blank of bulk low carbon steel; impacting the blank of bulk low carbon steel by using a compression device, so as to force the blank of bulk low carbon steel to perform a deformation at a high strain rate normally in a range of10 2 -10 3 /s, so that the microstructure of the blank of bulk low carbon steel is nano-structured, that is, bulk nano-structured low carbon steel is thus manufactured. In comparison with conventional low carbon steel, the nano-structured low carbon steel manufactured by the present invention has high tensile strength and fatigue limit, and the method of the present invention can be implemented by using not-so-complicated facilities, easily controlled and scaled up at an economic production cost. The present invention also relates to bulk nano-structured low carbon steel manufactured by the above-mentioned method, the bulk nano-structured low carbon steel preferably is a plate having a thickness of not less than 5 mm or a bar having a diameter of not less than 5 mm.
