It was shown, that coercive force and residual induction of sintering magnets are appreciably determined by conditions and type of thermal processing. By methods of roentgenographic and X-ray diffraction analyses structure and properties of amorphous - crystal powders Fe-РЗМ-В depending on the fraction size were investigated. It has been established, that the volumetric part of amorphous phase depends on cooling rate of powders (size of a fraction), that significally influences their magnetic properties. The magnets will be used in products of an electrotechnical and machine-building industry. Product Description popup.authors popup.nrat_date 2020-04-02 Close
