A method of manufacturing bulk nano-structured low carbon steel includes: 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 of 102-103/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. The bulk nano-structured low carbon steel is a plate having a thickness of not less than 5 mm or a bar having a diameter of not less than 5 mm.
