ABSTRACT

Taking into account the restrictions on the heat treatment of the amorphous alloys which are introduced by the ductile-brittle transition, it is very tempting to apply these effects to the amorphous matrix which would reduce the rate of the process of coalescence of submicropores and would result consequently in an increase of the temperature threshold of embrittlement which in fact means the increase of the thermal and time stability of the amorphous state of the alloys. Thermomechanical treatment is based on the application of a constant load creating uniaxial elastic stresses at temperatures considerably lower than the glass transition point of the amorphous alloys but slightly higher than room temperature. The thermal and time stability may be positively affected by the deposition of thin crystalline layers on the surface of ribbon specimens of the amorphous alloys.
