The research of dispersed precipitates in high-strength medium-carbon steel after tempering in the temperature range up to 600 °C was carried out. Amount of retained austenite decreases and cementite is forming instead of austenite by growth of the tempering temperature.

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 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 technological properties of the titanium alloy VT6 were studied. It is established that it can be successfully used in SPF/DB technology under conditions of low-temperature superplasticity at temperatures of 750-800° C. The model of the hollow blade of a three-layer structure was made from this alloy.
