ABSTRACT:
A method of reestablishing the deformability or malleability of embrittled amorphous alloys such as Fe.sub.40 Ni.sub.40 P.sub.20 or Fe.sub.20 Ni.sub.40 B.sub.20 or Cu.sub.64 Ti.sub.36. An alloy is first subjected to a first temperature for a specific first time interval. Subsequently, the alloy is subjected in a sudden manner to a second temperature for a specific second time interval. The effecting of change of the temperature of the alloy from the first temperature to the second temperature occurs at a rate of 100.degree. K./min. The first temperature is greater than the second temperature with the first temperature being in a temperature range between an embrittlement temperature and a crystallization temperature of the alloy.
