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.

摘要： A drill bit for cutting formation comprises a bit body, a plurality of cutters, a plurality of blades with pockets to accommodate the cutters respectively. Each of the plurality of cutters has an ultra-hard layer, two side facets extending obliquely inward from the substrate to a top surface of the ultra-hard layer, a convex portion between the two side facets. The convex portion comprises a transition surface and the transitional surface is convex as it extends between adjacent the two side facets. The curvature of the transitional surface varies along the cutter axis with the curvature at the cutting edge larger than the curvature of the cutter circumferential surface.
