Investigations of the influence of quality of the consumed electrode on the process of electroslag remelting under pressure of high-nitrogen steels

A new breakthrough in the creation of new materials and technologies for producing high-nitrogen steels (HNS) in Russia was made after the installation of an electroslag remelting unit under pressure (ESRP) and the development of FGUP “VIAM” of ESRP technologies. Due to the high demands placed on semi-finished products of HNS, high requirements are also imposed on ingots of ESRP and on consumable HNS electrodes. Investigations of metal used as consumable electrodes of the ingot are conducted, and requirements for its smelting are formulated.

Research the problems of filtration of a high-temperature nickel alloy ZhS32 against an impurity of silicon

The paper studies the filtration of high-temperature nickel alloys from harmful impurities when the melt is passed through a foam ceramic filter. A microstructure was studied with the determination of the local element composition of two samples of the high-temperature nickel alloy ZhS32 with a different silicon content (0,15 and 0,32%). It is established that impurities (sulfur, silicon, oxygen) are located near and in the pores of the material, which affects the strength characteristics. A microstructural study of a master alloy sample based on Y₅Si₃ was carried out. As a result of x-ray phase analysis, five phases were detected: Al₂Si₂Y, Al₃Si₂Y₂, Y₂AlSi₂, Al, Al₃Y, three of which contain silicon.

Research of process of out-of-autoclave formation semi-pregs on the basis of carbon fillers (review)

The increase in let-out volumes and especially dimensions оf products from composite, has demanded search of cheaper alternatives to avtoklave way of manufacturing of products. Ways of liquid vacuum formation dry preformеs impregnation binding have appeared the cheapest. The arisen problems of receiving high-quality products vacuum formation have led to development semi-pregs, representing fabrics or cordlike fillers which are duplicated with film of the binding. Many manufacturing firms of materials include in the nomenclature of the materials wide ruler semi-pregs. In work researches of processes of receiving polymeric composite materials (PСM) on the basis of developed semi-pregs by means of their formation by means of atmospheric pressure instead of autoclave for manufacturing of load bearing structures are considered. The interrelation of porosity of plastics, permeability, and some other parameters for the purpose of receiving PCM with minimal porosity and properties, approximate to avtoklave formation is investigated PСM.

Effect of preliminary etching of alloy ML5 before plasma electrolytic oxidation

Protection of magnesium alloys by method of plasma electrolytic oxidation is the most perspective. Protective properties of received coverings in big degree depend on surface structure of magnesium alloy. Availability on surface of alloy the phases containing aluminum, the Mg₁₇Al₁₂ type leads to covering forming with large amount of through defects. Preliminary etching of magnesium alloy in solution of alkali or fluoric acid significantly reduces porosity of covering and, therefore, increases its protective properties.

Repair of chemical oxide coating on carbon steel

Protective properties of the films formed on carbon steel in solutions of sulfur-containing substances, oxidizers and the tannin, and also the cathode processing in molibdenum solution are investigated. Protective ability of molibdenum film is higher than protective ability of the chemical oxide coating received in caustic solution. Possibility of repair of the damaged chemical oxide coating on carbon steel by way local cathode surface treatment of steel by rubbing by marker with molibdenum solution is shown.

Equipment for testing carrying out the strain-controlled low-cycle fatigue

Materials of structural elements of aircraft gas turbine engines during operation are subjected to a wide range of static and dynamic loads in a wide range of operating temperatures and durability. Therefore, to calculate the strength of the main parts of the engine and confirm their service life, it is necessary to have a large range of strength characteristics of metal materials under static and cyclic loading. The paper presents an overview of the characteristics of the strain-controlled low-cycle fatigue, obtained on Walter+Bai machines.

Equipment for bending tests constructive and similar samples welded hybrid panels of the wing

The article describes the various methods of static loading constructive-like specimen of a hybrid welded wing-skin panel for determining of strength characteristics. It is determined that selection of optimal loading method is influenced by the necessity of structure element resistance force determination or zone hybrid elements, the shear stress level in the design, test equipment and test complexity possible. It is shown that for the hybrid and welded panel zone investigation, including the quality and stability bonding technology determination, is preferred by bending loading scheme. Testing equipment is proposed in the form of two identical supports and a loading tip with rounded contact surfaces for three-point bending test of constructive-like specimen of a hybrid welded wing-skin panel with longitudinal stringers. Using the developed equipment allows bending loading for constructive-like specimen of a hybrid welded wing-skin panel both along the stringer and across. The sustainability of the constructive-like specimen hybrid wing-skin panels in three-point bending test using proposed testing equipment is provided by fixing the stringers and preventing the local crumpling and brittle fracture of the hybrid laminate strips during the test by reducing the contact stresses.

Strain-controlled testing advantages at static tension and repeated-static tension

The article presents advantages strain-controlled testing over force-controlled testing at static tension and repeated-static (fatigue) with a fixed deformation step. In addition to the traditional mechanical properties of materials (elastic modulus E, yield strength σ_0,2, tensile strength σ_в, permanent deformation δ), obtained from the stress-strain diagram at tensile test, introduction of additional characteristics (plastic deformation rate , material damage function of the specimen ω, damage velocity ) subject to stress-strain diagram with strain-controlled testing is suggested. The stress-strain diagram relationship with the envelope of the line when the strain-controlled repeated-static testing with a fixed deformation step introduced. Approaches to determining fatigue characteristics using test data in this manner at fatigue testing are showing. For 1441-T1 and 1163-ATB alloys under repeated-static testing, a characteristic effect is observe. A plastic deformation in a certain deformation range is realize discretely at the same stresses (similar to the yield plateau during tension). For alloy B-1481-T1, there is no similar effect.

The development of a solution for promotion of corrosion attack on aluminium alloys in a galvanostatic mode

Anodic dissolution of aluminum alloys in different solutions was studied as a promising approach to imitate corrosion of these alloys in natural environment. The solution, containing sodium nitrate, sodium sulfite and sodium chloride with «Ekomet» additive, which allows formation of pitting corrosion damage, comparable to observed in natural environment, during the anodic polarization, was developed. To promote not only the pitting corrosion, but also intergranular and exfoliation corrosion, additional chlorides were added to the solution. Alternative approach is to perform anodic dissolution in solution, containing nitrates, sulfites and
chlorides, first and then in sulfite-chloride solution.

Determination of thermophysical properties of epoxy materials during their curing

The results of the determination of the thermal conductivity and heat capacity of epoxy material directly during its curing, are given. when the phase state changes. As an object of research, an epoxy formulation based on epoxy-diane resin and modified aliphatic polyamine was used. Thermophysical properties were determined for different degrees of conversion at room and elevated temperatures. Depending on the degree of conversion, the value of volumetric shrinkage and residual stresses were also evaluated. It was found that during the curing process (i.e., when the degree of conversion is changed), the heat capacity decreases by 32% and more than three times the thermal conductivity increase.
