The phenomenon of formation and low-temperature diffusion transformation of metastable solid solutions with the release of dispersed particles of intragranular widmanstatten alpha phase in heat-resistant titanium alloys

In the article discussed the phenomenon of formation and low-temperature diffusion transformation of metastable solid solutions with the release of dispersed particles of intragranular Widmanstatten α in Russian heat-resistant titanium alloys. It is shown that the intragranular Widmanstatten alpha phase can be formed at the final stage of cooling of the semi-finished product after heat treatment to a solid solution, as well as a result of aging. Examples of heterogeneous structures in various semi-finished products and details are given. The change of mechanical properties of heat-resistant titanium alloys in connection with structural dispersion hardening is considered.

The influence of heating technology on the duration of the curing process of polymer composite materials

The results of experimental studies of the properties of organoplastics made using wet-wound technology using an epoxy binder are presented. Curing was carried out in two different ways: in the electric and microwave stoves when using two modes of increasing the temperature at a given value (single-stage and three-stage). It is shown that the use of microwave heating allows not only to significantly shorten the curing time, but also leads to an increase in the modulus of elasticity. Values of shrinkage, porosity and size of their standard deviation are given, itis experimentally established that use of microwave heating leads to increase in standard deviation.

Thermal stability of interfaces between the niobium matrix and γ-Nb5Si3 silicide in eutectic Nb–Si composites

The high thermal stability of the structure of the Nb–Si composite was substantiated experimentally and from the crystallochemical standpoints. The metallographic analysis of the microstructure of the composite in the initial state and after high-temperature homogenization is carried out. The phenomenon of microliquation of alloying elements has been studied. The directions of the predominant growth of the Nb matrix and silicide γ-Nb₅Si₃ in the process of directional crystallization are determined. By the methods of transmission electron microscopy, the orientational relationships between the niobium matrix and the silicide γ-Nb₅Si₃ were found: ˂111˃_Nbss||˂0001˃γ-Nb₅Si₃ and {110}_Nbss||γ-Nb₅Si₃. Based on the crystal-chemical analysis of the orientation and dimensional correspondence of the crystal structures of the matrix and silicide on the interfaces, the high structural thermal stability of the Nb–Si composite is substantiated.

Stickiness and possibility of using prepregs for automated technologies (review)

In this review, the stickiness property of prepregs is considered, which affects the technological parameters in the process of laying out the workpiece parts from polymer composite materials. Various methods for determining stickiness, advantages and disadvantages of these methods are considered. It is shown that stickiness of prepregs depends on the temperature and storage conditions of prepregs. Dependence of the stickiness of prepregs on the temperature makes it possible to ensure easy separation of the prepreg from the substrate and to pass through the belt tape at a reduced temperature without adhering to the rollers, and then good adhesion to the tooling and to the prepreg layers due to heating to the temperature of high tackiness. The material VKU-25 developed in VIAM will allow to carry out the automated technology at manufacturing of preparations of details from polymeric composite materials.

Biomorphic composites: a promising class of materials (review) Part 1. History of creation, methods of the production

Overview and history for biomorphic composites (a wood-based promising class of mate-rials) were presented. Methods for the preparation of such composites (liquid silicon infiltration, gaseous Si or SiO infiltration, SiO₂ precursor infiltration with subsequent carbothermal reduction) were introduced. In all cases wood pyrolysis with strict control of operating tempe-rature ensuring preparation of crack-free monoliths is used as the initial stage of the process.

Biomorphic composites: a promising class of materials (review) Part 2. Mechanical properties, application

Analysis of mechanical properties for biomorphic composites was performed. It was shown that properties in axial direction exceeded the ones in radial and tangential directions. This fact can be explained by the preservation of microstructure on going from a piece of wood to a biomorphic composite. Prospects for application of biomorphic composites in various industrial fields (as catalyst support, high-temperature gas filtration materials, armor materials as well as in medicine, radio electronics, and power engineering) were discussed.

Abradability and erosion resistance of seals in turbine engine air-gas channel

The main properties of abraded sealing materials defining efficiency of their application in flowing part of gas turbine engines, are abradability which can be provided by relative wear of sealing material and material of rotor details, and its erosion resistance, which has to be rather high to guarantee engine operation during the set resource. Abradability and erosion resistance are defined by strength properties of materials and are inversely proportional sizes therefore creation of effective abraded sealing materials is one of the most complex and actual challenges of aviation materials science. Results of researches of abradability and erosion resistance of modern aircraft engines of sealing materials applied in designs are given in article, and also the pilot materials developed by VIAM Federal State Unitary Enterprise

Development the set of methods measurements of the chemical composition of nickel-based alloys

Heat-resistant nickel alloys are materials used to manufacture a wide range of gas turbine engine parts. The level of refractory strength of the heat-resistant nickel alloys is determined by their chemical and phase composition, as well as by the manufacturing techniques used, which ensure the formation of a given material structure. An important factor in the industrial production of the heat-resistant nickel alloys and in the development of new-generation alloys is the ability to control the chemical composition of the cast bar stock and finished products from the heat-resistant nickel alloys by modern methods of spectral analysis. The development of a set of methods for measuring the mass fraction of elements in heat-resistant nickel alloys by mass spectrometry with inductively coupled plasma, optical emission and X-ray fluorescence analysis, makes it possible to control the content of alloying and microalloying elements and various impurities.

The usage of fractographic analysis to diagnostic the causes of destruction of products from medium-carbon steel

The reasons of destruction of products from medium-carbon steels (steel 60, steel 55 and steel 51HFA) are investigated and established. It was established that the main material of the products (cables and springs) met the requirements of the normative documentation on the composition, structure and content of non-metallic inclusions. The destructions were caused by the action of stresses exceeding the permissible (in the first and third cases). Differences in the structure of the breaks, obtained from the action of complex static load and cyclic loads, both at low tension levels and at elevated ones are shown.

Determination of oxygen and nitrogen in nickel alloy powders

In this work, the determination of the oxygen and nitrogen content in powders of nickel alloys EP648, VPr50 and VG159 was carried out by reductive melting in a current of an inert carrier gas, followed by detection of oxygen in an infrared cell and nitrogen in a conductometric cell of a Leco TC-600 gas analyzer. During the experiments, various catalysts were used – tin and nickel, necessary for the complete extraction of oxygen and nitrogen from nickel alloy powders. Preparation of a sample for analysis is described.

Influence of the coating type on the damping ability

In this research we investigated the possibility of reducing the vibration amplitude of the free end of a flat sample during vibration tests on the first bending form due to the application of different types of surfaces on the sample shank when it is fixed in the technological capture on the equipment for the vibrodynamic stand. The dependence of the q-factor of the oscillating system on different types of coatings, the thickness of which is ~30 microns, and the tribological characteristics of the coatings are

investigated. It is shown that the solid-lubricant coating VFP-5 increases damping, reducing the amplitude of the free end of the sample during vibration tests on the first bending form. The coating based on the aluminum alloy VSDP-28, does not significantly reduce the amplitude of the free end of the sample and the ion-plasma coatings of the TiN/CrN, Ti–TiN and SDP-2 systems reduce the damping properties of samples from the titanium alloy VT6.
