Popis: In an aging austenitic iron-based alloy (Fe–35.8Ni–2.6Ti), when the deformation temperature decreases from 573 to 203–77 K, a sharp intensification of anomalous processes of the dissolution of nanoparticles of the coherent γ'-Ni3Ti phase has been detected upon the interaction with dislocations. This is connected with the suppression (at cryogenic temperatures) of alternative diffusion processes of the precipitation of particles initiated by point defects.
