  • Enhancing magnetic properties of amorphous alloys by rolling
    Patent number: 4053332
    Abstract: A nickel based amorphous alloy in elongated ribbon form is passed between two rollers to obtain approximately a one third reduction in thickness. The rolled alloy samples may then be subjected to elastic tensile loading, which tends to increase remanence and decrease coercivity. The rolling process tends to reduce the unloaded remanence and thereby to improve the load versus remanence range sensitivity by a considerable amount.

  • Enhancing magnetic properties of amorphous alloys by annealing under stress
    Patent number: 4053333
    Abstract: A nickel based amorphous alloy in elongated ribbon form is subjected to a stress in the range of 20 to 40 kilograms per square millimeter, and is heated to temperatures below the melting point, preferably in the range of 200.degree. C. Such heating under stress is maintained for a period of time, whereupon the material is cooled. There results a residual enhancement of the magnetic properties which occur by application of stress, but which are extinguished when the stress is removed.

  • Method of making amorphous metallic alloys having enhanced magnetic properties by using tensile stress
    Patent number: 4053331
    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.
