Abstract: front page image
(EN)An Fe-based soft magnetic alloy is provided. The Fe-based soft magnetic alloy according to an embodiment of the present invention is represented by empirical formula FeaBbCcCud wherein a, b, c and d indicate the at%(atomic percent) of corresponding elements, 78.5≤≤a≤≤87.0, 12≤b+c≤≤21 and 0.5≤≤d≤≤1.5, and comprises α-Fe and metal compounds formed with Fe and at least one element of B, C and Cu. Accordingly, the alloy has a high saturated magnetic flux density, excellent high-frequency characteristics and low coercivity, and thus can be very easily employed as a compact and light high-performance and high-efficiency part. Also, the present invention incurs a very low production cost and can be mass-produced by facilitating alloy production by allowing easy control of components, contained in the alloy, during the alloy production process. Accordingly, the present invention can be widely applied as a magnetic part of electric and electronic devices such as a high-power laser, a high-frequency power supply, a high-speed pulse generator, an SMPS, a high-pass filter, a low-loss high-frequency transformer, a high-speed switch and wireless charging.
(FR)La présente invention concerne un alliage magnétique doux à base de Fe. L'alliage magnétique doux à base de Fe selon un mode de réalisation de la présente invention est représenté par la formule empirique FeaBbCcCud où a, b, c et d représentent le pourcentage atomique (% at) d'éléments correspondants, 78,5 ≤≤ a ≤≤ 87,0, 12 ≤ b + c ≤≤ 21 et 0,5 ≤≤ d ≤≤ 1,5, et comprend des composés α-Fe et des composés métalliques constitués de Fe et d'au moins un élément parmi B, C et Cu. Par conséquent, l'alliage présente une induction magnétique hautement saturée, d'excellentes caractéristiques haute fréquence et une faible coercivité, et peut ainsi être utilisé très facilement en tant que pièce compacte, à haute performance de lumière et à haut rendement. En outre, la présente invention entraîne un coût de production très faible et peut être produite en série en facilitant la production d'alliage en permettant un contrôle facile des composants, contenus dans l'alliage, pendant le processus de production d'alliage. En conséquence, la présente invention peut être largement appliquée en tant que pièce magnétique de dispositifs électriques et électroniques tels qu'un laser à haute puissance, une alimentation électrique haute fréquence, un générateur d'impulsions à grande vitesse, une SMPS, un filtre passe-haut, un transformateur haute fréquence à faible perte, un commutateur à grande vitesse et une charge sans fil.
(KO)Fe계 연자성 합금이 제공된다. 본 발명의 일 실시예에 따른 Fe계 연자성 합금은 실험식 FeaBbCcCud 로 표시되고, 상기 실험식에서 a, b, c 및 d는 해당 원소의 at%(atomic percent)이며, 78.5≤≤a≤≤87.0, 12≤b+c≤≤21, 0.5≤≤d≤≤1.5이며, α-Fe, 및 Fe와 B, C 및 Cu 중 적어도 하나의 원소간 형성되는 금속화합물들을 포함한다. 이에 의하면, 높은 포화자속밀도, 우수한 고주파 특성 및 낮은 보자력을 가져서 고성능/고효율의 소형/경량화된 부품으로의 용도전개가 매우 용이하다. 또한, 본 발명은 제조단가가 매우 낮고, 합금에 포함되는 성분이 합금의 제조과정에서 쉽게 컨트롤됨으로써 합금의 제조가 용이하여 대량생산이 가능함에 따라서 대출력 레이저, 고주파 전원, 고속펄스발생기, SMPS, 고주파 필터, 저손실 고주파 트랜스포머, 고속 스위치, 무선충전 등의 전기, 전자기기의 자성부품으로 널리 응용될 수 있다.
