Beschreibung
Zusammenfassung:Iron-boron-silicon ternary amorphous alloys having high saturation magnetization, high crystallization temperature and low coercivity are obtained by selecting a narrow range of iron, boron and silicon. Figure 4 shows a composite of saturation magnetization contour lines of various iron, boron and silicon alloys at room temperature (30 DEG C) having a magnetization of at least about 174 emu/g at about 30 DEG C, an intrinsic coercivity after annealing of less than 0.03 oersteds and a crystallization temperature of at least about 320 DEG C. The iron-boron-silicon amorphous metal alloys of the present invention fall within the shaded regions A, B, C, D, E, F, A, indicated with the preferred alloys lying within the region a, b, c, d, a.
