The features of structural and phase transitions during severe plastic deformation (in Bridgman anvils) of the amorphous Ti{sub 50}Ni{sub 25}Cu{sub 25} alloy have been studied by X-ray diffraction and transmission electron microscopy. Application of successively increasing deformation has revealed three cycles of successive phase transitions from amorphous to crystalline state and vice versa. The results obtained are explained in terms of the superposition of the different channels of elastic energy dissipation, which are activated during severe plastic deformation.
