Abstract

PURPOSE: To provide high permeability alloy the permeability of which is extremely thermally stable by rendering amorphous an alloy contg. Fe and/or Co, Nb, one or more out of V, Ta, Ti, Zr, Cr, Mo and W, and B or B and Si in a specific ratio.
CONSTITUTION: An alloy of a compsn. represented by formula (T1-a-bNbaMb)1-c Xc. In the formula, T is Fe and/or Co, M is at least one of V, Ta, Ti, Zr, Cr, Mo and W, X is B or B and Si, the Si content ≤25 atomic%, each a and b=0.005W 0.10, c=0.15W0.35, and the Fe content is 3W8 atomic% to the total amt. of Co, Fe, Nb and M. A molten alloy of the above compsn. is sprayed with high press. Ar gas from the nozzle of a quartz tube to the space between rolls rotating at high speed. Thus, the alloy is rapidly cooled to obtain a ribbon-shaped high permeability amorphous alloy.
