Abstract
Magnet cores pressed using a powder of nanocrystalline or amorphous particles and a pressing additive should be characterized by minimal iron losses. These particles have first surfaces represented by the original strip surfaces and second surfaces represented by surfaces produced in a pulverization process, the overwhelming majority of these second particle surfaces being smooth cut or fracture surfaces without any plastic deformation, the proportion T of areas of plastic deformation of the second particle surfaces being 0≦T≦0.5.
