In present work a method for obtaining technically useful Fe-26%Cr-16%Co-2%Mo-2%W hard magnetic alloy from powder raw materials is proposed. The distinctive feature of the method is the lowered sintering temperature of powder compacts (1100 - 1200 °C).

High temperature corrosion resistant coatings of metallic glasses FeNiCrWMoCoCB has been synthesized on the steel 1035 surface by electrospark machining in the granules medium consisting of crystalline materials of different composition.

Numerical simulation of necking in tension cylindrical sample with simplified elastic-plastic material properties and large deformations. For experimental verification of the calculated data was carried out by sample testing tensile check deformations on the surface of the sample in real time by the method of digital image correlation.

It was processed by electron beams of a surface of a titanium alloy and the increase of fatigue life is established. Scanning and transmission electron microscopy has been used to study the structure of a titanium alloy modified with electron beams and destroyed by fatigue.

Gas-abrasive wear resistance of silicon carbonitride SiCxNyHz and boron carbonitride BCxNy films obtained by CVD methods was studied.

This work presents the results of the effect of preliminary heat treatment on the features of the formation of ultra fine-grained structure of Al-Cu-Mg alloy obtained by means of high pressure torsion in Bridgman anvils. It was established the nature of grain refinement and hardening in the aged or quenched alloys.

Storage of dislocations at plastic deformation of polycrystalline FCC alloys of Cu-Al and Cu-Mn is studied. It is determined that storage of dislocation (<ρ>) at plastic deformation depends from stacking fault energy (γ sf).

The influence of various modes of thermal cycling treatment on the microstructure and properties of the ferromagnetic Ni47Mn42In11 alloy was studied.

It was shown that rapid cooling leads to the formation in Babbite Sn11%Sb5,5%Cu a structure with small, intermetallic particles uniformly distributed in the matrix phase. Computer modeling predicts its high wear resistance in the operation of a large-sized sliding bearing.

By the method of molecular dynamics the structural changes in Ni-Al bimetal particles during the passage of shock waves were studied. Investigated the possibility of forming pores near the interphase boundary metals and related effects.

The finite-dimensional scaling method was used to calculate the critical heat capacity index α. It is established that the growth of the energy parameters of the multi-spin interaction substantially affects the critical heat capacity index.

The effect of modify by rare earth metal dysprosium in combination with heat treatment on microstructure and mechanical properties on compression testing of intermetallic β-solidifying γ(TiAl) alloy was studied. The image shows a microstructure of alloy Ti-45Al-6(Nb,Mo)-0,2 B-1Dy, where the observed layer DyAl2-phase and Dy2O3 oxide particles.

Has been shown that in the train of cooling of In–4.5 mass% Cd alloy the pocket martensite structure below martensite FCC-FCT temperatures, consisting of colonies of tetragonal slat plates are being formed.

Phase transitions of tetragonal L4-8 graphites to diamond-like LA7, LA8, and LA10 phases have been investigated.

The composites of Ti-C-H-Cu system were obtained by mechanosynthesis in liquid carbon media (petroleum ether, xylene), followed by magnetic pulse compaction of the powders. Structural-phase composition was investigated and density, microhardness and wear resistance of the composites were determined.

Dependence of the DB localization parameter, β, energy, E, frequency, ω, on the amplitude of the DB.

Microstructure of the aluminum oxynitride powder after chemical purification, obtained by the SHS-metallurgy method . The by-products (Al, AlN) and impurities (Mo) were removed. The average composition is given in the article.
