接近于等原子成分的ＦｅＣｏ合金是一类典型的软磁材料,其居里温度和饱和磁感强度最高,而且磁致伸缩也高,所以具有十分广泛的工业应用。这种合金之所以具有这样优异的性能,可能与其以Ａ2→Ｂ2相转变形式的远程有序化密切相关。然而,Ｂ2相结构不仅仅决定了优越的合金磁特性...
FeCo alloy close to the atomic composition is a kind of typical soft magnetic material, which has the highest Curie temperature and saturation magnetic induction and high magnetostriction, so it has a very wide range of industrial applications. The reason why such an alloy possesses such excellent properties may be closely related to its remote ordering in the A2 → B2 phase transformation. However, the B2 phase structure not only determines the superior magnetic properties of the alloy ...
