Magnetic nanocomposite materials including iron, rare earth elements, boron, refractory metals and cobalt which have favorable magnetic properties and are suitable for making bonded magnets are disclosed. Compositions of the present invention can be of the formula: (N
A plurality of relatively high magnetic permeability strips are interleaved to form layers of a closed loop differential transformer core. Although the material of each layer by itself may have a relatively square hysteresis loop, the core formed of a plurality of interleaved layers of such material ...
Magnetic nanocomposite materials including iron, rare earth elements, boron, refractory metal and, optionally, cobalt are disclosed. Neodymium and lanthanum are preferred rare earth elements. The amounts of Nd, La, B and refractory metal are controlled in order to produce both hard and soft magnetic ...
A method of forming a magnetically anisotropic powder includes the steps of forming a substantially spherical powder having a major magnetic phase and an average particle size of less than about 200 microns, diffusing hydrogen into the spherical powder at elevated temperatures in an amount sufficien ...
A permanent magnet alloy consisting essentially of R.sub.2 Fe.sub.14 B, wherein, R is a combination of rare earth elements consisting essentially of, in atomic percent, neodymium 3 to 11 and balance holmium. The alloy may include optional additions of the rare earth elements gadolinium up to 10%, te ...
The present invention relates to highly quenchable Fe-based rare earth magnetic materials that are made by rapid solidification process and exhibit good magnetic properties and thermal stability. More specifically, the invention relates to isotropic Nd—Fe—B type magnetic materials made from a rapid ...
Carbon addition to the rapidly solidified, preferably melt spun, alloy system of Sm(Co, Fe, Cu, Zr) provides for good isotropic magnetic properties. Importantly, these alloys are nanocomposite in nature and comprise the SmCoC
