| Abstract: | The influence of γ radiation on the thermal and acoustic effects in amorphous Ti−Ni−Cu alloys is investigated. On the basis
of the results obtained, a mechanism by which γ quanta affect the structure of amorphous metal alloys (AMA) is proposed. In
the interaction of a γ flux with AMA, the energy is redistributed and accumulates at intercluster boundaries. Then, when restructuring
of all the intercluster boundaries is complete, restructuring of locally regular clusters begins; this leads, in turn, to
restructuring of the intercluster boundaries. Further increase in radiation dose again triggers the mechanism of intercluster-boundary
restructuring, but at a different level. This is evident in the oscillatory fluctuation in the activation energy of relaxation
processes and of phase transformation from amorphous to crystalline structure.
