Title
(EN) Soft magnetic alloy powder and preparation method thereof
(ZH) 软磁合金粉末及其制备方法
Abstract
(EN) The invention provides soft magnetic alloy powder and a preparation method thereof, the alloy expression of the soft magnetic alloy powder is FeaCobSEc, in the alloy expression, SE comprises at leastone of B, P, C and Si, and satisfies 20 < = a < = 80, 20 < = b < = 80, 2 < = c < = 15, and a + b + c = 100. By means of the mode, the soft magnetic alloy powder has the advantages of being high in saturation magnetization intensity, low in coercive force, low in eddy current loss and the like, can be applied to the working environment where materials with high saturation magnetization intensity are required, and widens the application range of soft magnetic alloy.
(ZH) 本发明提供了一种软磁合金粉末及其制备方法,所述软磁合金粉末的合金表达式为FeaCobSEc,所述合金表达式中,SE包括B、P、C和Si中的至少一种,满足20≤a≤80,20≤b≤80,2≤c≤15,a+b+c=100。通过上述方式,本发明的软磁合金粉末,具有高饱和磁化强度、低矫顽力、低涡流损耗等特点,可应用于要求高饱和磁化强度材料的工作环境中,拓宽了软磁合金的应用范围。
