    摘要： A method of manufacturing a high permeability amorphous magnetic alloy is disclosed. In the method amorphous magnetic alloy ribbon prepared by quenching a melt of raw material is annealed at an elevated temperature lower than a crystallization temperature of the alloy, in a magnetic field. During the annealing, the alloy ribbon and the direction of the magnetic field are relatively rotated with each other. The method is especially useful to an amorphous magnetic alloy having high saturation magnetic induction where the magnetic Curie temperature of the alloy usually exceeds the crystallization temperature of the alloy.

    摘要： A method of manufacturing an amorphous alloy in which a molten mixture of raw materials making up the amorphous alloy is first prepared, and then introduced between a pair of oppositely rotating rolls where the molten material is rolled and quenched into a film. The conditions under which the rolling and quenching occur are carried out under the following conditions: ##EQU1## where: Y is the roll pressure per unit width of the film in metric tons per centimeter,C.sub.o is a constant determined by Young's modulus and the thermal conductivity of the material of the rolls,A is the rotational speed of the rolls in r.p.m.,R is the diameter of the rolls in centimeters,X is the thickness of the film in microns,T.sub.cry is the crystallization temperature of the amorphous alloy in .degree.C.,T is the temperature of the rolls in .degree.C., and where ##EQU2## where the rolls have the diameters of R.sub.1 and R.sub.2 centimeters, respectively.
