Abstract: Provided are a rare-earth permanent magnet whose magnet density after sintering is very high and a method for manufacturing a rare-earth permanent magnet. Thus, a magnet raw material is milled into magnet powder, and then, a compound 12 is formed by mixing the magnet powder thus milled with a binder. Next, the compound 12 thus formed is subjected to a hot-melt molding onto a supporting substrate 13 so as to form a green sheet 14 molded to a sheet-like shape. Thereafter, while the green sheet 14 thus molded is softened by heating, magnetic field orientation is carried out by applying a magnetic field to the green sheet 14 thus heated; and further, the green sheet 14 having been subjected to the magnetic field orientation is calcined by a vacuum sintering, which is further followed by a pressure sintering to produce a permanent magnet 1.

Abstract: Methods of making sintered articles from powder metal carbide compositions by additive manufacturing techniques are described herein. Sintered carbide articles fabricated by such additive manufacturing techniques, in some embodiments, exhibit densities equaling articles formed according to conventional techniques employed in powder metallurgy. For example, a method of manufacturing an article comprises providing sintered cemented carbide powder comprising a hard particle phase including tungsten carbide and a metallic binder phase and forming the sintered cemented carbide powder into a green article by one or more additive manufacturing techniques. The green article is sintered to provide a sintered article having density greater than 90% theoretical full density, wherein the green article has a density less than 50% theoretical full density prior to sintering.

Abstract: A process for synthesizing metal nanopowders by introducing metal carbonyl into an induction plasma torch. By taking advantage of the much lower dissolution temperature of carbonyl as opposed to the high melting temperature of conventional metal powder feeds less torch power is required. Moreover, in contrast to current powder production techniques utilizing electrode based plasma torches, the induction plasma torch does not introduce contaminants into the nanopowder.

Abstract: A method of fabricating a medical implant component. The method may include the steps of producing a substrate from a first material wherein the substrate has a bearing portion, spraying particles of a second material onto the bearing portion in accordance with a predetermined spraying technique to provide a coating thereon, and subjecting the coated bearing portion to a hot isostatic pressing process, a vacuum sintering process, or a controlled atmospheric sintering process. The first material may be the same as or different from the second material. The predetermined spraying technique may be a thermal type spraying process such as a plasma spraying process or a high velocity oxygen fuel spraying process.
