Abstract
A criterion for estimating the time of mechanical degradation of met-quenched amorphous alloys in the climatic temperature range is proposed. To determine the time interval of embrittlement, it is necessary to obtain two heat release spectra, one of which corresponds to the initial (after melt quenching) state of an amorphous alloy and the other, to the same alloy after annealing at given temperature and time parameters. The proposed criterion is used to show that the introduction of phosphorous into the alloy composition leads to accelerated degradation of the mechanical properties (embrittlement) of commercial amorphous alloys.
