Abstract:
(EN) This soft magnetic powder is represented by composition formula FeaSibBcPdCue with the exception of unavoidable impurities. In the composition formula, a, b, c, d and e satisfy 79 ≤ a ≤ 84.5 at%, 0 ≤ b < 6 at%, 4 ≤ c ≤ 10 at%, 4 < d ≤ 11 at%, 0.2 ≤ e < 0.4 at%, and a + b + c + d + e = 100 at%.
(FR) L'invention porte sur une poudre magnétique à aimantation temporaire représentée par la formule générale FeaSibBcPdCueà l'exception des impuretés inévitables. Dans la formule de la composition, a, b, c, d et e sont tels que 79 ≤ a ≤ 84,5 en %, 0 ≤ b {t; 6 en %, 4 ≤ c ≤ 10 en %, 4 {t; d ≤ 11 en %, 0,2 ≤ e {t; 0,4 en %, et a + b + c + d + e = 100 en %.
(JA) 軟磁性粉末は、不可避不純物を除き組成式FeSiCuで表される。上述の組成式において、79≦a≦84.5at%、0≦b<6at%、4≦c≦10at%、4<d≦11at%、0.2≦e<0.4at%、且つ、a+b+c+d+e=100at%である。
