Title (EN) SOFT MAGNETIC FLAT POWDER
(FR) POUDRE PLATE MAGNÉTIQUE DOUCE
(JA) 軟磁性扁平粉末
Abstract:
(EN) The purpose of the present invention is to provide a soft magnetic flat powder with which it is possible to prevent oxidation during the flattening of metal powder and achieve a low coercive force. In order to achieve the purpose, there is provided a soft magnetic flat powder comprising a plurality of soft flat particles, wherein each of the plurality of soft magnetic flat particles is a metal particle containing, in mass%, 78-83% of Fe, more than 0% and at most 13% of Si, more than 5.0% and at most 13% of Al, and 1.0-5.0% total of at least one among Cr, Ni, Mo, Cu, and Ti, with the remainder comprising Fe and inevitable impurities.
(FR) L'objet de la présente invention est de produire une poudre plate magnétique douce avec laquelle il est possible d'empêcher l'oxydation lors de l'aplatissement de poudre métallique et d'obtenir une faible force coercitive. Afin d'atteindre l'objet, l'invention concerne une poudre plate magnétique douce comprenant une pluralité de particules plates magnétiques douces, chaque particule de la pluralité de particules plates magnétiques douces étant une particule métallique contenant, en % en masse, de 78 à 83 % de Fe, plus de 0 % et au plus 13 % de Si, plus de 5,0 % et au plus 13 % d'Al, et de 1,0 à 5,0 % au total d'au moins un parmi le Cr, le Ni, le Mo, le Cu et le Ti, le reste contenant du Fe et des impuretés inévitables.
(JA) 本発明は、金属粉末の扁平化加工時の酸化を防ぎ、低い保磁力を実現することができる軟磁性扁平粉末を提供することを目的とし、かかる目的を達成するために、複数の軟磁性扁平粒子を含んでなる軟磁性扁平粉末であって、前記複数の軟磁性扁平粒子のそれぞれが、質量%で、Fe:78%以上83%以下、Si:13%以下(0は含まない)、Al:5.0%超13%以下、Cr,Ni、Mo、Cu、Tiのうち少なくとも1種類:合計1.0%以上5.0%以下を含み、残部がFe及び不可避的不純物からなる合金粒子である、軟磁性扁平粉末を提供する。
