Abstract: A products having at least a portion thereof with a nanocrystalline microstructure, and methods of producing such products. The method generally entails machining a body to produce a polycrystalline chip having a nanocrystalline microstructure. The chips produced by the machining operation may be in the form of particulates, ribbons, wires, filaments and/or platelets. The chips may be consolidated (with or without comminution) to form a product, such that the product is essentially a nanocrystalline monolithic material consisting essentially or entirely of nano-crystals, or of grains grown from nano-crystals. Alternatively, the chips may be dispersed in a matrix material, such that the product is a composite material in which the chips are dispersed as a reinforcement material. According to a particular aspect, a monolithic article can be formed entirely from a single chip by deforming the chip and/or removing material from the chip.

Abstract: A process by which nanostructured monolithic bodies can be produced in a single continuous operation, as opposed to multi-stage deformation processing. The process generally entails continuously producing a chip (24) having a nanostructured microstructure by engaging a solid body (10) with a cutting edge (18) of a tool while the solid body (10) and the cutting edge (18) move relative to each other, and simultaneously extruding the chip (24) in the immediate vicinity of the cutting edge (18), such as with a constraining member (16), as the chip (24) is separated from the solid body (10) by the cutting edge (18) to continuously plastically deform the chip (24) and produce a nanostructured monolithic body (26) immediately downstream of the cutting edge (18). The shape and size of the chip (24) can be simultaneously controlled by the extrusion process so that the nanostructured monolithic body (26) has a predetermined geometry. The nanostructured monolithic body (26) can be in the form of a product suitable for immediate use, or undergo further processing to yield a product.
