| description | Provided is an Fe-based soft magnetic alloy. An Fe-based soft magnetic alloy according to an embodiment of the present invention is represented by the empirical formula XaBbSicCudMe, wherein: X includes Fe and at least one element among Ni and Co; M includes at least one element among Nb and Mo; and a, b, c, d, and e indicate the atomic percents (at%) of corresponding elements, in which 15.0≤b+c≤19.0, 0.5≤d≤1.5, and 2.0≤e≤5.0; and X is included as the remainder. Accordingly, the Fe-based soft magnetic alloy has high saturation magnetic flux density and low magnetic loss characteristics, and thus can be very easily used in various parts using magnetic materials. In addition, since the effect of heat treatment conditions can be minimized during the realization of uniform and small crystal grains after heat treatment, process conditions can be easily designed, so that the Fe-based soft magnetic alloy is very suitable for mass production.
L'invention concerne un alliage magnétique doux à base de Fe. Un alliage magnétique doux à base de Fe selon un mode de réalisation de la présente invention est représenté par la formule empirique XaBbSicCudMe, dans laquelle : X comprend Fe et au moins un élément parmi Ni et Co ; M comprend au moins un élément parmi Nb et Mo ; et a, b, c, d et e indiquent les pourcentages atomiques (% at) des éléments correspondants, avec 15,0 ≤ b+c ≤ 19,0, 0,5 ≤ d ≤ 1,5, et 2,0 ≤ e ≤ 5,0 ; et X est compris comme étant le reste. En conséquence, l'alliage magnétique doux à base de Fe possède une densité élevée de flux magnétique de saturation et de faibles caractéristiques de perte magnétique, et peut ainsi être très facilement utilisé dans diverses pièces utilisant des matériaux magnétiques. De plus, étant donné que l'effet de conditions de traitement thermique peut être rendu minimal au cours de la réalisation de grains cristallins uniformes et petits après le traitement thermique, les conditions de traitement peuvent être facilement élaborées, de telle sorte que l'alliage magnétique doux à base de Fe convient très bien pour une production de masse.
