Co-based magnetic alloy and magnetic members made of the same

Abstract:

Disclosed is a Co-base magnetic alloy excellent in high-frequency magnetic properties, of which chemical composition is represented by the following general formula, by atomic %, (Co1-aFea)100-y-cMnullyXnullc, where Mnull is at least one element selected from the group consisting of V, Ti, Zr, Nb, Mo, Hf, Sc, Ta and W; Xnull is at least one element selected from the group consisting of Si and B; and a, y and c are defined by the formulas of a

Abstract(Chinese):

公开了一种高频磁性能优异的钴基磁性合金，其特征在于，以下述通式表示化学组成按原子％表示（Co1-aFea）100-y-cM'yX'c，其中M' 是选自V，Ti，Zr，Nb，Mo，Hf，Sc，Ta和W中的至少一种元素; X'是选自Si和B中的至少一种元素; 和a，y和c分别由<0.35,1.5 <= y <= 15和4 <= c <= 30的公式定义。合金的合金结构的至少一部分由平均粒径不大于50nm的晶粒构成。该合金的相对初始磁导率不大于2000，适用于大电流零电压和电磁屏蔽材料等抗噪声成分，逆变器变压器，有源滤波器的扼流线圈，天线，平滑扼流线圈，用于激光器的电源，用于加速器的脉冲功率磁性元件。
