ARTICLE FOR PRODUCING ULTRA-FINE POWDERS AND METHOD OF MANUFACTURE THEREOF
A multistage centrifugal atomizer comprises an outer shell that contains an inlet port and an outlet port and that encloses a tundish, a first inclined rotating surface and a second inclined rotating surface. The first inclined rotating surface is opposedly disposed to the second inclined rotating surface. The inlet is used to introduce a molten material into the multistage atomizer and the outlet is used to remove ultrafine particles having a D50 of less than 20 micrometers.

METHOD OF MANUFACTURING PERMANENT MAGNETS
A continuous method of manufacturing permanent magnets and the permanent magnets created thereby. A fine powder is created from a combination of magnetic metals. The powder (a metal alloy) is placed in a non-magnetic container of any desired shape which could be, for example, a tube. The metal alloy and tube are swaged while a magnetic field is applied. Once swaging is complete, the metal alloy and tube are sintered and then cooled. Instead of sintering, a bonding agent can mixed into the powder. Following cooling, the metal alloy is magnetized by placing it between poles of powerful electromagnets with the desired field direction. The process of the invention enables mass-produced, cost-effective PM products, which are more robust, easily assembled into products, enables new wire like shapes with arbitrary magnetization direction. The process enables mass production of permanent magnets of any desired cross section, produces permanent magnets continuously that may be cut to any length, and may, in an embodiment, result in directional magnets.
