The fine structure of spontaneous deformation jumps and jumps initiated by both the shock action on a deformation device and a strong fast-changing magnetic field (up to 2.7 MA/m) has been investigated in metals and alloys at liquid-helium temperatur

Consideration is given to a multilevel structural approach to the occurrence of local instability zones under the conditions of active deformation of a superconducting titanium alloy (Tc = 5.4 K). It is noted that the dislocation nanostructural level

The influence of the dislocation forest on the work hardening curves during basal slip as well as the structure of the local shear bands in Zn single crystals have been investigated. The forest dislocation were introduced into the single crystals in

Regularities in the behavior of athermal dislocational anomalies of microcontact spectra of zinc single crystals are established. It is shown that they arise due to emission of terahertz waves by dislocations. In this case hexagons of basis dislocati

The regularities of the growth twin boundary behavior in Zn bicrystals under shear stress have been investigated. The aim of this work was to study the possibility of the movement of a growth twin boundary by the generation and motion of twinning dis

A dislocation spectrum of the electron-phonon interactions (EPI) of zinc single crystals is obtained for the first time. It is shown that dislocations are a source of hypersonic waves. Possible mechanisms of energy dissipation in vibrations of the ne

Electrical heating in a liquid nitrogen medium alters the structural state of polycrystalline titanium. It is shown by the methods of resistometry, X-ray photography, and metallography that, in treatment by current, grains grow by collective recrysta

We investigated the change of the structural state when a current pulse was passed through the high-modulus alloy ABM-1 situated in a medium of liquid nitrogen. Current pulses heat the material and bring about thermal stresses that lead to a reductio
