Description
Technical field
The present invention relates to a kind of alloy inhales ripple micropowder material, more particularly to a kind of alloy of addition Rare Earth Y b inhales ripple micropowder and its preparation technology.
Background technology
With developing rapidly for military new and high technology, Stealth Technique on Aircraft stealth becomes more and more important.While widely using with electronic equipment, electromagnetic radiation is increasingly serious so that absorbing material uses more and more extensive in military and civilian.
Excellent absorbing material not only requires that microwave absorbability is high but also the performances such as suction bandwidth of being eager to excel.Traditional absorbing material mainly has ferrite-type and magnetic metal（Alloy）Micropowder etc., ferrite saturation magnetization under 1-18GHz frequency ranges is low, and microwave magnetic permeability is less, and matching thickness is thicker（Centimeter Level）, therefore Ferrite Material is subject to great limitation in the application of the frequency range.And soft magnetic metal inhales ripple micropowder because Curie temperature is high, temperature stability is good, if soft magnetic metal is worn into into micropowder by Technology, the atom for making alloy surface increases, and the special construction of high concentration crystal boundary and crystal boundary atom can cause material under the radiation of electromagnetic field, and atom, electron motion aggravate, promote magnetization, electromagnetic energy is set to be heat energy, so as to increased the absorption to electromagnetic wave, current magnetically soft alloy micropowder mainly has Fe, Co, Ni and its alloy powder etc..
4f shells are discontented with rare earth atom electron outside nucleus layer, and with magnetic moment, 4f shells " buried " are not affected by conduction electronics and adjacent to dot matrix to a great extent in atom, the magnetic moment size of rare earth atom or ion not only with atom or iongI is factor-related, also with atom total angular momentumJ It is relevant, these unique properties make rareearth magnetic material produce breakthrough in many fields, such as rare earth permanent magnet, giant magnetostriction material, magneto-optic and magnetic refrigerating material, rare earth specificity will also affect the mechanism of absorption of electric wave absorbing materials, such as complex permeability and natural resonant frequency, therefore the addition of rare earth and its compound has become the effective way for improving absorber characteristic.The present invention is added in Fe-Ni based alloys by choosing the rare earth element of certain content, and the alloy for preparing a kind of excellent performance inhales ripple micropowder.
The content of the invention
