The influence of process parameters of selective laser melting on the structure of aluminum alloy Al–Si–Mg system

Selective laser melting (SLM) technology allows the manufacture of geometrically-complex parts, including aluminum alloys, which can find their application in various industries. To provide high performance products, an important task is to obtain dense (with low content of defects), fine structure of the material. One possible solution is the choice of the optimal modes of production parts using SLM. The article presents the results of a study of the influence of SLM process parameters on the porosity of the synthesized samples of aluminum alloy system Al–Si–Mg. Shows the change in the structure depending on the energy density, scan speed, distance between the tracks and laser power.

Research of the influence of parameters of isothermal deformation and heat treatment on structure and mechanical properties punchings from alloy VT6ch

Isothermal punching is the perspective cost-efficient form-building technological process for the titanium alloys, allowing to lower materials consumption and labor input of the manufacturing in comparison with the traditional multitransitional manufacturing techniques of details from forgins and plates. One of the problems of this work is research of the influence of modes of deformation and thermal processing on structure and mechanical properties of isothermal punching from alloy VT6ch. It has been shown that isothermal die forging on the final step of deformation leads to elongation increase up to 14%. Further heat treatment (recrystallization annealing) results in globular-lamellar structure formation which is most favorable in order to provide ultimate tensile strength values not less than 995 MPa.

Effect of cooling rate on phase composition and structure of VT6 titanium alloy after hydrogenating annealing

The effect of cooling rate on structure formation processes upon hydrogenating annealing of VT6 alloy (Ti–6,25Al–4,1V% wt.) has been studied, the mentioned processes being governed by mechanism and kinetics of transformations in hydrogen-containing β-phase. It has been shown that cooling rate of 1 K/s gives the opportunity to reduce diffusion-based decomposition of hydrogen-containing β-phase in the samples subjected to hydrogenation at 850–900°С to a concentration of 0,6% wt. H and higher. Thus a single-phase β-structure is formed at room temperature, which is uncommon for the VT6 alloy upon equilibrium conditions.

Changes in the surface properties of titanium alloy VT20 in the chemical removal of operational carbon pollution

For the first time investigated the influence of foreign and domestic chemical technologies removal of operational carbon pollution on the complex properties of the surface of the heat-resistant titanium alloy VT20. Visually, the gravimetric method, and using scanning electron microscopy and X-ray microanalysis of samples evaluated cleaning performance against carbon polution. The change in surface roughness, microhardness and surface activity of purified samples. It is established that when cleaning samples from carbon pollution chemically, an increase in the microhardness and a reduction in surface activity may occur, as compared to those for the initial samples. By its technological characteristics VPr16 solder picked possibility of reconditioning by soldering after the removal of carbon polution from the surface of titanium alloy VT20 chemical means.

Heat-resistant putties on base silicone resins

The comparative rate analysis of thermo-oxidative destruction of the film-forming agent of various nature is carried out and necessity of applying polyorganosiloxanes for the development of heat-resistant putties is proved. The choice of the inorganic heat-resistant fillers providing the minimum internal stresses in coatings with putties taking into account influence of fillers on the rate of thermo-oxidative destruction polyorganosiloxanes is reasonable. Results of assessment of technological, physic-mechanical, rheological and dielectric properties of KO-0035, KO-0066, KO-0067, KO-0070 putties, and also their heat resistance when heating in isothermal conditions and in gas-dynamic flow are given.

Physical and physico-mechanical properties of antifriction organoplastics based on combined fabric filler and epoxy binder

An antifriction organoplastic based on epoxy binder and combined fabric filler including polytetrafluoroethylene and polyimide fibers was investigated. Data on its basic physical properties, physico-mechanical properties under uniaxial tension were obtained. The stress-strain curves were analyzed, the temperature dependences of the modulus of elasticity, strength and elongation at tension were established. Antifrictional organoplastic was a polymer composite material with 0,25–0,30 mm thickness and 1,55 g/cm3 density, has resistance to water and aviation petroleum products. It was shown that in the investigated temperature range from -40 to +60°С the organoplastic was characterized by strength of 30–110 MPa, elastic modulus of 0,7–4,5 GPa and deformations of 3–22%. According to the results of the research, antifriction organoplastics can be successfully used as a coating of a given size and shape for the modification of friction surfaces without significant weight gain and changes in t

Preparation of carbon fibers to interphase coating deposition for ceramic matrix composites

The comparative results of surface coating removal from the carbon fiber, which determine the efficiency of interphase coating deposition and ceramic matrix composite manufacturing, are discussed. The physical-chemical and thermal analysis, tensile strength measurements and microstructure of carbon fillers with surface coating and after its removal were carried out. It was shown, that the most optimal method from technological point of view is the surface coating removal by annealing of carbon fiber at static air atmosphere at 400°С.

Corrosion protection of magnesium alloys polysulphide sealants

Studied the protective properties of polysulfide sealants UT-32NT and VITEF-1NT on the samples of magnesian alloy MA8 after exposure to the tropical chamber during for 7 months, salt spray chamber during for 2 months, andML5 after fuel TS-1. It was found that, when working in an environment of air and tropical climate sealants VITEF-1NT or UT-32NT (film thickness of 1,5–2 mm) are suitable for protecting alloy MA8 oxidized as a sheet and in contact with the rivets on KFО-30 ground or sealant. Sealants VITEF-1NT or UT-32NT after exposure in the fuel TS-1, containing water in the form of a separate phase, have weak adhesion to a magnesian alloy of ML5 oxidized and do not protect it from corrosion.

Force, deformation and energy criteria of destruction

Force, deformation and energy criteria of destruction are considered. It is shown that in elastic area communication between characteristics of destruction has linear character. Size defining criterion is the size of the specific volume energy necessary for education or development of the available surface of destruction. It is thus considered, what not all spent at formation of a new free surface energy goes on formation of a surface. The part of energy dissipates in the form of heat, sound and electromagnetic waves. At the expense of it the body reduces the potential energy and thus resists to further destruction. The destruction model in which a formula Griffitsa is a special case is offered. Work is executed within implementation of the complex scientific direction 3.3. «Technology of forecasting of properties, modeling and implementation of modern processes of designing and production of products from nonmetallic and composite materials with use of the digital methods compatible

Anisotropy of elastic properties tensile of single crystals in Nickel-based superalloys

For the 2012–2015 period at FSUE «VIAM» carried out important experimental work, aimed at obtaining the strength characteristics of the single crystals with the orientation , and of the most promising Nickel-based superalloys. This work is devoted to study the anisotropic characteristics of elasticity in tension (рoisson's ratio and static modulus of elasticity) single crystal Nickel-based superalloys VZHM7 and VZHM8 with crystallographic orientations (CGO) , , in the temperature range 20–1000°C.
