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 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.

On the presented time dependences of pressure change and electrical resistance of the sample during the ETE of the reaction mixture W-Ni-Al, it is evident that the preheating time was 2.6 seconds, and the duration of the thermal explosion stage was 0.5 seconds.

A method for the construction of initial atomic models of nanocrystals with extrinsic dislocations in grain boundaries for molecular dynamics simulations is developed. The method is used to determine atomic structures and energies of grain boundaries in columnar f.c.c. nanocrystals with [112] column axis.

The recrystallization mechanism after ECP was deduced to be similar to that operating during conventional static annealing. The microstructural changes were explained in terms of Joule heating and similar observations for static recrystallization.
