Abstract

The effect of the addition of Ti, V, Cr, and Mn on the magnetic properties of a nanocrystalline soft magnetic Fe–Zr–B alloy has been investigated. The addition of the elements increases both the crystallization temperature and the grain size of α-Fe. After crystallization, these elements are observed in both the α-Fe grains and the residual amorphous matrix. It has been found that V is a useful element to control magnetostriction by keeping the saturation magnetic flux density [formula omitted] high. The simultaneous addition of V and Mn increases [formula omitted] The alloys with high [formula omitted] above 1.75 T, show good soft magnetic properties as well; the [formula omitted] alloy exhibits high [formula omitted] of 1.75 T and high permeability [formula omitted] of 31 000, and the [formula omitted] alloy exhibits high [formula omitted] of 1.78 T and high [formula omitted] of 23 000. These high [formula omitted] values are almost the same as that of a Fe-6.5 wt % Si alloy. The alloys also exhibit low core loss. Therefore, nanocrystalline Fe–V–(Mn)–Zr–B alloys are expected to be applied to power electronic devices such as power transformers.
