High-temperature annealing of low-activation chromium-manganese austenitic steel leads to discontinuous precipitation of dispersed M23C6 carbides along grain boundaries, micro- and nanotwin boundaries. At coherent twin boundaries, the growth of particles during annealing is limited by cross-sectional dimensions of the twin plates.

After 10 passes of friction stir processing (FSP) three phases are observed - the aluminum matrix, NiO and Al3Ni particles. It should be noted that there are no traces of NiO remaining inside the Al3Ni particles. Thus, an acceleration of the chemical reaction occurred between the 4th and 10th passes of friction stir processing (FSP), leading to the formation of a significantly larger quantity of Al3Ni and Al2O3 particles.

The influence of warm multidirectional isothermal forging on the grain structure and mechanical properties of the high-nitrogen austenitic steel VNS-53-Sh has been studied. It has been shown that the average grain size was reduced to ~ 6 μm after forging compare to initial state due to the formation of small grains at the boundaries of the original grains and fragmentation of them. It promote an increase in strength properties.

Structural behavior and hardening of the high-strength aluminum alloy 1965 after isothermal rolling at the temperature of liquid nitrogen with reductions in the range of 30-70% was studied for two pre-quenched conditions - the homogenized ingot and further hot-forged billet. In spite of differences in the initial structure parameters, the structure transformations in both the alloy states under cryorolling were preferably associated with the formation and development of the dislocation-cellular structure of the matrix.

The maximum effect of increase in electric capacitance of the composites with 4 wt % Au and 5 wt.% MnxOy with respect to capacitance of MWCNT is 1.2 and 2.9, respectively, in the region of the low scan rates.

Grain refinement and texture changes caused by HPT increase strength and ductility. HPT does not worsen the RBC hemolysis and ML viability of pure Zn. HPT insignificantly increases the degradation rate.
