Abstract
1. Способ получения нанокристаллического магнитного порошка для создания широкополосных радиопоглощающих материалов, включающий термическую обработку исходного материала в виде аморфной ленты из магнитомягких сплавов в течение 30-90 мин с охлаждением на воздухе, измельчение термообработанной ленты до фракции 3-5 мм с последующим измельчением в высокоскоростном дезинтеграторе, отличающийся тем, что термическую обработку исходного материала ведут до образования в нем наноструктуры.2. Способ по п.1, отличающийся тем, что термическая обработка исходного материала производится при температуре (0,35-0,37) TLig, а измельчение в высокоскоростном дезинтеграторе ведут до получения порошка с размером фракции 15-35 мкм.1. A method of producing a nanocrystalline magnetic powder for creating broadband radar absorbing materials, including heat treatment of the starting material in the form of an amorphous tape of soft magnetic alloys for 30-90 minutes with cooling in air, grinding the heat-treated tape to a fraction of 3-5 mm, followed by grinding in high speed a disintegrator, characterized in that the heat treatment of the starting material is carried out until a nanostructure is formed in it. 2. The method according to claim 1, characterized in that the heat treatment of the starting material is carried out at a temperature of (0.35-0.37) TLig, and grinding in a high-speed disintegrator is carried out to obtain a powder with a particle size of 15-35 microns.
