    摘要： Amorphous metal alloys are employed in a magnetic head as core materials in the present invention. Such alloys are generally composed of M and Y, wherein M is at least one of Fe, Ni and Co and Y is at least one of P, B, C and Si. The amorphous metal alloys used are marked by a combination of the desirable properties of conventional permalloy with those of conventional ferrites.

    摘要： An iron base alloy is described which contains low amounts of alloying elements and is suitable for use as a transformer core material. The alloy is characterized by a (110) texture, and a primary recrystallized and normal grain growth microstructure. The process for obtaining the oriented structure is either a two stage or a three stage process in which the final cold reduction effects only a moderate reduction in cross-sectional area to finish gauge. In all cases the alloy is subjected to a final anneal at a temperature below the Ac1 temperature of the alloy.
