摘要： This application concerns a magnet having a magnet body as well as a method for manufacturing such a magnet. The magnet body has a first region with first magnetic properties and a second region with second magnetic properties that are different to the first properties. Owing to the manufacturing process of the magnet body, the relative location of the first region and the second region within the magnet body is freely predeterminable.

摘要： The invention shows how powder injection molding may be used to form a continuous body having multiple parts (21,23), each of which has different physical properties such as magnetic characteristics or hardness. This is accomplished through careful control of the relative shrinkage rates of these various pads. Additionally, care is taken to ensure that only certain selected physical properties are allowed to differ between the parts while others may be altered through relatively small changes in the composition of the feedstocks used. An additional application of the present invention is a process for forming, in a single integrated operation, an object that is contained within an enclosure while not being attached to said enclosure. This is accomplished by causing the shrinkage rate of the object to be substantially greater than that of the enclosure. As a result, after sintering, the object is found to have detached itself from the enclosure and is free to move around therein.

摘要： A method is provided for making soft magnetic parts from particulates of ferrous material. The methods includes the following steps. Providing a plurality of ferrous particles and coating at least one substantially uniform layer of from about 0 wt.% to about 15 wt.% of a metal onto each of the particles. The coated particles are consolidated to form a part, and the part is heated at a temperature and for a time period sufficient to promote the formation of intermetallic phases between the metal layer and the ferrous particle at the boundary therebetween. The intermetallic phases have an electrical resistivity of greater than about 100 ohms/mil-ft.
