New Technology to Produce Sharp Edges in Metals
The present disclosure is directed to systems, compositions, and methods for manufacturing objects with sharp edges having a high strength and hardness. To form the sharp edge, an object can be subjected to a compressive force that locally deforms the object to create the sharp edge. In some embodiments, deformation can occur by passing the material through a system of one or more opposed tapered rolls having one or more tapering angles for deforming the material. The tapered rolls can rotate and drive the material downstream to a next opposed pair of tapered rolls. The tapered rolls deform the material by changing the material microstructure, compressing the grains of the material in a predetermined location to create a more homogeneous microstructure. The local modification of the resulting microstructure increases the homogeneity as well as the hardness and strength of the material and prevents cracking and/or chipping of the material.
