During the cyclic deformation the energy dissipation zone covers a significant amount of the titanium sample and the zirconium alloy one in the ultrafine-grained state. For the coarse-grained and fine-grained states the growth of thermal energy has a localized character in the active zone of the samples. Cyclic loading of the titanium sample and the zirconium alloy in the ultrafine-grained state is accompanied by a qualitative change in the energy absorption dissipation process.

The method of consolidation of metal powder is proposed, this method consists in applying a layer of metal powder on the surface of the detail, compressing the powder at a point between the workpiece and the electrode, and sintering at this point by electric pulse. Sequential dot by dot sintering leads to the formation of a new layer and allows to obtain bulk materials.

The main mechanisms of plastic deformation under high-speed compression and tension of CoCrFeMnNi single crystals are the formation of stacking faults and bands with a hcp lattice, the subsequent twinning occurs only upon stretching. Deviation from the equiatomic composition significantly improves the physical and mechanical properties of this alloy.

The contact zone of the composite plates for the shell of the petrochemical reactor (coke drum) produced by explosive welding and made of steel 08Cr13 and steel 12CrMo has multilayered structure. The carbon segregation provokes the eutectoid decomposition that causes formation of colonies of rod-shaped carbides. As a result, there are two risk zones: the melted zone (2) and the segregation zone (3).

At cooling from T~ 400 K a La0.82Ca0.18MnO3 single crystal undergoes the transition from pseudocubic O* phase to Jahn-Teller O' phase and the reverse transition from the O' to low temperature O* phase. It is surprising that low values of the internal friction are observed for crystal phase O' with significant Jahn-Teller distortions of oxygen octahedra.
