ABSTRACT:
The problem of working an amorphous alloy is overcome by heating the alloy at a rate of temperature increase above about 1000.degree. C. per minute. The amorphous alloy is worked by homogeneous deformation after its temperature has been very rapidly increased to above the softening temperature of the alloy. Desirable magnetic properties of the alloy are preserved by working the alloy in this fashion and also tool life is extended.
