Influence of heat treatment on the formation of structure and properties in the nickel-beryllium alloy 97NL-VI

The influence of heat treatment on the formation of structure and properties in the nickel-beryllium alloy 97NL-VI is considered in the article. The dissolution in the structure of the γ-matrix of the NiBe hardening intermetallic phase as a function of the quenching temperature is analyzed. It is found that when aging, the Guinier–Preston zones are initially formed, contributing a small contribution to the hardening, which later transform into a metastable γʹ-phase. The optimum aging temperature interval with a high complex of mechanical properties and a low level of specific electrical resistance has been specified.

Wrought intermetallic titanium ortho alloy doped with yttrium. Part 1. Research on ingot microstructure and rheological curves plotting

The article contains the results of microstructure investigations in the cross section of an ingot from wrought intermetallic titanium ortho alloy doped with yttrium. The effect of heat treatment in a two-phase (b/В2+α₂)-area on microstructure of the yttrium doped ortho alloy ingot has been studied. Thermal analysis has been performed with differential scanning calorimetry (DSC) curves plotting which specify phase transformation temperatures of the alloy in focus. Rheological curves for the upset cylindrical samples have been plotted, which revealed deformation strain reduction with upsetting temperature increase from 850 to 1050°C. It has been shown that doping of ortho alloys with rare-earth elements (REE) results in rolling temperature increase.

Effect of heat treatment on mechanical properties and structure of high-strength metastable β-titanium alloy with experimental composition

The effect of various modes and technological parameters of hardening heat treatment on mechanical properties and structure of sheets from an experimental composition of a high-strength metastable β-titanium alloy doped with rare-earth element yttrium have been studied.

It has been shown the possibility of wide variation within parameters and morphology of structural constituents of the experimental alloy composition. The experimental alloy can be effectively strengthened both by conventional heat treatment and low-temperature thermo-mechanical treatment (LTMT). Long-term low-temperature ageing makes it possible to provide high level of strength characteristics with satisfactory values of elongation and impact toughness.

Casting methods for a thin-walled part from silumin (review)

The process of casting of thin-walled shaped casting from the aluminum alloy AK7ch. with the use of two methods of casting: sand casting and investment casting was observed in this article. The plastic foundry pattern equipment got by 3D printing technology is used in both cases. The differences in the methods of casting were revealed, which affected the quality of the part. A comparative analysis of the experimental results was carried out. Based on the results of the experiment, an optimal method for casting a thin-walled casting «Housing» from the alloy AK7ch. was selected.

Study of formation of intermetallic matrix structure based on heat-resistant nickel alloys

The paper presents the results of a study of the structure formation of in-thermetallide-oxide high-temperature metal composite materials based on nickel alloys reinforced with monocrystalline aluminum oxide plastids. Samples for research were obtained by the method of reaction impregnation. nickel powder with a diameter of 5–10 µm and nanosized nickel alumina particles with a diameter of 1–10 nm were used as matrix-forming agents. The results of the study of the microstructure and phase composition of samples of metal composite materials with different NiAl particle content (10; 15 and 20%) are shown. In order to identify individual intermetallic phases, microhardness studies were conducted.

Influence of hardener OS-17 on exploiting properties of the varnish covering UR-231

In the study operational properties of coverings on the basis of varnish UR-231 are investigated. Comparison tests of varnish UR-231 with hardeners OS-17 and diethylene glycol urethane (DGU), and also coverings on their basis are carried out. Varnish UR-231 put on samples of alloy D16-AT and samples of printed circuit boards according to specifications 6-21-14–90. Comparing analysis of the received results was carried for the purpose to define possibility of replacement of DGU hardener on hardener OS-17 in interests of reduction of technological process of painting of varnish coatings at the expense of reduction of time of varnish filmforming.

Feature of receipt anti-icing coating (review)

Literature analysis on possibilities to obtain anti-icing coatings is presented. Solid surface wetting regimes and properties of superhydrophobic coatings, coatings based on elastomers, organogels, SLWL- and SLIP-surfaces are discussed. Influence of wetting angle and surface roughness on ice-to-surface adhesion and time of water droplet freezing is shown.

It seems that smooth surfaces based on elastomers and superhydrophobic coatings increase time of water droplet freezing and decrease ice adhesion. Such coatings supposed to be effective anti-icing coatings. SLWL- and SLIP-surfaces also possess low ice adhesion and high icing durability but have some deficiencies connected with mechanical and operational characteristics and need to be modified.

Definition of area of the maximum shear deformations for CFRP samples on Iosipescu method, with use of optical system of measurements

In this work researches nature of change of area of localization of the maximum shear deformation have been provided when testing carbon plastic specimens in four planes on the ASTM D5379 standard (GOST R 56799). In article there are two kinds of carbon fiber-reinforced polymer. First based on carbon fabric and second based on carbon roving (with orientation of fibers only in one direction). Measurements of deformation field of sample were carried out by means of optical system of digital image correlation (DIC). The question of influence of different length of site of measurement of deformation as for digital extensometers (DIC), and for pasted strain gages, on reliability of the received values also is considered.

Research of causes of destruction of the impeller and fan wheel from alloy AK4-1

Complex research of two cases of operational destructions of details of difficult configuration from alloy AK4-1 (impellers and fan wheels) is conducted. By methods of optical and electron microscopy, chemical analysis and mechanical tests it is evaluated macro- and microstructure, chemical composition and nature of destruction of details is studied. It is established that destruction of the impeller and wheel of the fan has occurred at action of cyclic load. Destruction of details was promoted by availability of rough surface and micro damages (scratches from machining) in zone of the increased tension.
