Using a static model of two-speed motion of the gas suspension in gunning-lance it is shown how the powder concentration, carrier gas pressure,particle number density, equivalent diameter, shape factor, differential velocity, and dynamic phase slip have an effect on the aerodynamic drag coefficient, interfacial interacting force, inclusion volume fraction of gas phase, and velocity of soaring. 

The main factor of a high-temperature abrasive wear of a rotary crusher is the geometrical one, which is characterized by the depth of penetration ratio hв to the radius of an abrasive particle ra , i.e. hв / ra. The second factor is the physical-mechanical one, which is characterized by the ratio of tangential strength of molecular bond τa to the material yield point σт , i.e., τa / σт . For the support of an abrasive wear without microcutting the sum of the ratio has to satisfy the following condition hв / ra + τa / σт ≤ 0,5.

The research results on the properties of gray cast iron, having been modified by various additives FS-45, depending on the duration of melt irradiation by nanosecond electromagnetic impulses (NEMI) are submitted in the paper. The properties of cast irons modified with FS-45 vary in the extreme dependence on the duration of the melt irradiation by NEMI. Appropriate duration will contribute to the improvement of the mechanical and operating properties of gray cast iron. 

The authors mark the specificity and develop the conditions of similarity of control systems with prognostic physical model. 

In the process of getting glass foam crystalline material on the low-temperature technology it was revealed the formation of new structural elements that increase the strength of the final foam. It is established that the amorphous interpore partition of the material possesses a globular structure, and the nanoglobules themselves have a complex multilevel structure. 

The features of the changes of the real and imaginary components of the impedance in the restructuring of the amorphous soft magnetic Co66Fe4Nb2.5Si12.5B15 wires due to direct current annealing have been revealed. The difference in the behavior of the frequency dependences of the impedance component with increasing current density annealing has been determined. The frequency range with a dominant sensitivity of the imaginary component of impedance to the structural changes in the wire compared to the real one has been detected. The results are explained on the basis of the ideas on restructuring the atomic and domain structure of the wire caused the annealing by a direct current, subject to the differences in the behavior of the components of the dynamic magnetic permeability with changing the frequency of the alternating current. 

The results of the analysis of the structure and phase composition, mechanical, tribological and corrosion properties of commercially pure titanium VT1-0 subjected to a combined treatment that combines electroexplosive alloying and subsequent irradiation by high-intensity electron beam are considered. Identified modes of treatment, allowing to multiple increases controlled properties of the material and discusses the physical reasons contributing to this. 

The paper presents the results of the investigated features of the deformation of amorphous and nanocrystalline metallic alloys under the impact of an electric current. It has been established that the transmission of the pulse electric current leads to a transient release of mechanical stress in the loaded samples with its subsequent restoration. The dependence of the release of mechanical stress on the current density is obtained.
