K. B. Povarova, A. E. Morozov, A. A. Drozdov

High-melting (Tmelt = 2100 °C), heat-resistant monoaluminide RuAl, lighter (ρ = 7.97 g/cm3) than Ni-superalloys, is considered as a promising candidate material for working at high temperatures and relatively small loads in high-speed gas oxidation flows at temperatures above not only the working temperatures, but also the melting points of both nickel superalloys and nickel and titanium aluminides. RuAl is also an ideal candidate for potential applications for protective coatings. Part I of the article discusses the principles of selection of alloing systems and methods for producing casting single-phase or heterophase alloys of RuAl, features of changes in their structural-phase state during cold and warm deformation, presents data on mechanical properties in a wide range of temperatures, resistance to oxidation and the effects of a number of corrosive environments, erosion resistance in plasma.

 

Keywords: monoaluminide ruthenium, cast alloys, production, structure, properties, deformation, plasticity, heat resistance, resistance in corrosive environments.

The results of experiments on the impact of fast helium ions (Ei ~ 100 keV) and helium plasma (v ~ 2·107 cm/s) on a silicon single crystal plate in the Plasma Focus (PF) device “Vikhr” with radiation power density in the range of q ≈ 106 – 1011 W/cm2 are presented. It have been shown that at low values of q = 106 – 107 W/cm2 the damageability of silicon is due to its surface sputtering mainly in the zone of mechanical defects, while with more intense irradiation (108 < q ≤ 1011 W/cm2) the processes of melting and evaporation of the surface layer occur with the formation of structural defects in the form of waves, flows, bubbles, craters and micro-cracks. The specifics of damage of the Si plate at high power density and a large number of pulsed beam-plasma effects (q ≥ 109 W/cm2, N = 50) are described. It is associated with the formation of a brittle fine-crystalline surface layer, which is easily separated from the base material and disintegrates in the form of a powder of particles of micron and nanoscale size. This result is a consequence of the action of thermal stresses in combination with the implantation of helium ions into the material as well as the possible influence of shock waves generated in the Si target during hard irradiation regimes. The presence of copper, carbon, and nitrogen on the silicon surface after its beam-plasma treatment, as well as an increase in the electrical resistivity on the irradiated side and backside of the plate, are noted. The results obtained are discussed taking into account the features of the experiments in the PF setup.

 

Keywords: Plasma focus device, silicon single crystal, high-power pulsed helium ion and helium plasma flows,  material damageability.

Conductive material based on copper powder with improved mechanical properties

A. G. Meilakh, Yu. V. Kontsevoi, S. Yu. Melchakov, A. V. Dolmatov

By means of pressing, rolling and sintering in hydrogen at a temperature of 800 °C, conductive powder materials based on copper in the Cu-Fe-Al system were obtained. The influence of individual components and their mixtures on compaction, structure and basic functional properties of composites was studied. Electrical conductivity, hardness, and strength (yield strength) were measured depending on the technological parameters of production: pressing pressure — 200 – 700 MPa, rolling deformation — 40 – 85 %, dispersion of iron powders — fractions < 50 and 63 – 100 µm, and concentrations of iron powders — 5 – 10 % and Fe2Al5 intermetallic compound — 2.5 – 5 %. The best combination of physicomechanical properties was found for the composite (wt.%) 92.5 % Cu + 2.5 % Fe2Al5 + 5 % Fe using iron powder of 63 – 100 µm fraction. It was shown that dispersed hardening of copper with Fe2Al5 particles and filling its structure with iron fibers formed by rolling provided a high relative density of 98 – 99 % and indexes of the strength characteristics of the composite: hardness HB — 980 MPa, yield strength — 150 MPa with electrical conductivity — 71 % from the conductivity of copper.

Keywords: metal powders, composite materials, dispersion hardening, fibrous structure, physical and mechanical properties.

Rheological properties of composites based on aluminum hydroxide and low- and high-density polyethylene blends

N. B. Arzumanova, F. A. Mustafayeva, N. T. Kakhramanov

The results of the study of the rheological characteristics of low- and high-density polyethylene blend in the ratio of 50:50 and its aluminium hydroxide-filled composites are presented. The influence of the concentration of aluminium hydroxide, temperature and shear stress on the regularity of changes of the effective viscosity and shear rate has been established. Rheograms of low- and high-density polyethylene blend in the ratio of 50:50 and composites based on it are presented. The dependence of viscosity on temperature in Arrhenius coordinates is determined, according to which the “apparent” activation energy of viscous flow for the initial low- and high-density polyethylene blend and its aluminium hydroxide-filled composites varies in the range of 6 – 19 and 11 –31 kJ/mol, respectively. A universal temperature-invariant characteristic of the viscosity properties of low-and high- density polyethylene blend in the ratio of 50:50 and its aluminium hydroxide-filled composites, which allows to predict the change in the melt viscosity of composites in a wide range of shear rates and stresses, was drawn. It is shown that with an increase in the concentration of aluminum hydroxide in the polymer mixture to 5wt.% the value of the shear rate remains almost unchanged relative to the initial low- and high-density polyethylene blend (50/50). Rheological studies of the melt of polymer materials were carried out in accordance with the standard ASTM D1238 on capillary rheometer CEAST MF50 (INSTRON, Italy) in the temperature range of 190 – 250 °C and in the load range of 3.8 – 21.6 kg.

Effect of Fe doping on structural, magnetic and electrical characteristics of manganites of the system
La0.7Sr0.3Mn0.9Zn0.1–xFexO3 (0 ≤ x ≤ 0.1)

Experimental data on the structure and properties of manganites of the La0.7Sr0.3Mn0.9Zn0.1-xFexO3 (0 £ x £ 0.1) system are presented. Manganites were synthesized by ceramic processing and annealed under conditions ensuring the achievement of stoichiometric oxygen content. All manganites have a rhombohedral structure. The substitution of iron for zinc leads to the increase of unit cell volume and average cation-anion distance in octahedral sublattice, which is due to the rise of Mn3+ ions concentration at the expense of Mn4+ content as a result of charge compensation processes. The angles between Mn–O–Mn bonds are practically unchanged. Curie point, magnetization and metal-semiconductor transition temperature as a function of iron content are characterized by the presence of a maximum. Maximum value of the resistance of manganite with x = 0.1 is 800 – 1000 times higher than maximum values of the resistance of other samples in the studied temperature range. Тemperature dependences of magnetic permeability provide the evidence for the existence of magnetic inhomogeneities in manganites, especially in the samples with x = 0 and x = 0.1, which may be due to nonuniform distribution of Zn2+ ions and the presence of ferromagnetic and paramagnetic clusters. These data are consistent with the results of the study of EPR spectra containing additional and (or) broadened lines. Peculiarities of the dependences of studied manganites properties on the iron content are explained by the influence of a number of competing factors: decrease of the Mn4+ ions concentration and the probability of antiferromagnetic interaction between them; change of the number of disturbed exchange bonds between Mn4+ and Mn3+ ions; variations of magnetic inhomogeneities characteristics.

Keywords: manganites, zinc, iron, unit cell, magnetization, Curie point, metal-semiconductor transition, EPR, clusters.

Formation of superhydrophobic coatings on the track-etched membrane surface by the method of electron-beam dispersion of polymers in vacuum

L. I. Kravets, M. A. Yarmolenko, A. A. Rogachev, R. V. Gainutdinov,

Methods for the formation of one- and two-layer superhydrophobic coatings on the surface of the hydrophilic poly(ethylene terephthalate) track-etched membrane using the method of electron-beam deposition of polymers in vacuum are considered. It is shown that the use of this method with the applying of ultra-high molecular weight polyethylene as a target for deposition makes it possible to obtain hydrophobic and highly hydrophobic coatings with morphologically developed structure on the membrane surface. The deposition on their surface of the thin layer of polytetrafluoroethylene by the method of electron-beam deposition leads to the formation of a superhydrophobic coating. To obtain a one-layer superhydrophobic coating on the membrane surface, polytetrafluoroethylene was used as a target. It is shown that an increase in the water contact angle of the coating in this case is due to the increase in the roughness of the deposited polytetrafluoroethylene layer. The resulting composite membranes can be used in membrane distillation processes for the desalination of seawater.

Keywords: track-etched membranes, electron-beam deposition of polymers in vacuum, ultra-high molecular weight polyethylene, polytetrafluoroethylene, superhydrophobic polymer coatings, composite membranes.
