After crystallization the Sn-Y-O films show hydrogen gas-sensitivity properties. Particularly, the injection of hydrogen into argon at 350 °C leads to decreasing of electrical resistance more than 60% for Sn-Y-O nanocrystalline thin film with Y concentration of 4.8 at. %.

The microstructure and local mechanical properties of zones of 12Cr18Ni10Ti steel and a titanium alloy VT1-0 with an intermediate copper insert joint were carried out. The stress–strain diagrams for zones of the joint are received using the original technique for determining coefficients of the “stress–strain” diagram.

At step of deformation from e = 0.5 to e = 4.6, the stage of nucleation of the ω phase is observed only in area of the α-phase, which have a favorable crystallographic orientation. The formation of groups of planar defects in the ω phase is a mechanism for the compensation of elastic stresses during lattice transformation α → ω under conditions of high quasihydrostatic pressure. The figure shows the dark-field image in the reflex (001)ω of the deformed structure at angle of anvil of Bridgman φ=15 grad (e=1.5) of pseudo-single crystal of zirconium

Hydrogenation leads to the formation of a gradient state in the steel Fe-17Cr-10Mn-7Ni-1V-0.09С-0.65N (wt.%): thin (<15 μm) brittle surface layer is formed on the side surfaces of the samples, which cracks during plastic flow; the central parts of the samples are destroyed in transgranular viscous mode similar to the samples destroyed without hydrogen charging. The thickness of the brittle surface layer increases and the character of the destruction changes with increasing duration of saturation of the samples with hydrogen in tension: from brittle mixed (transgranular and intergranular) after saturation for 8 and 16 hours to fully intergranular for 32-50 hours of hydrogen-charging.

In electro-technical textured tape, the formation of optimum narrow zones of plastic deformation across the texture axis decrease the size of magnetic domains 3-4 times. This leads to decrease the speed of motion of the domain boundaries and to considerable reduces by 25% of magnetic losses during magnetization reversal of the material.
