ABSTRACT:
The magnetic properties of amorphous metallic alloys are improved significantly by application of stress to the alloy material. Selected alloys in ribbon form are subjected to controlled tensile stress, whereupon resulting magnetic properties are superior to corresponding conventional crystalline materials. So stressed, the amorphous alloy material may be applied to advantage as transformer cores, magnetic delay lines, magnetic computer cores, and the like.
