Research of γ/γ' interphase boundaries of ZhS36 single-crystal containing impurity, by using the methods of transmission electron microscopy and X-ray microanalysis

The processes which are taking place on interphase dividing surfaces γ/γ' in heat-resistant carbon-free nickel alloy for single-crystal casting ZhS36-VI are studied. It is established that harmful impurities (sulfur, phosphorus, lead) enrich interphase boundaries, reducing their durability. At simultaneous influence of elevated temperature and tension the amount of sulfur on interphase boundaries increases that accelerates alloy durability loss and reduces time to destruction. Introduction of a lanthanum which also enriches interphase boundaries slows down this process.

Keywords: heat-resistant nickel alloy, inner dividing surfaces (interfaces), harmful impurities, microalloying.

Study of mechanical properties and fracture mode of new sparingly alloyed cold-resistant steel with yield strength not less than 690 MPa

Urpose of the present research is to determine the optimal heat treatment parameters that ensure yield strength over 690 MPa in combination with impact toughness of at least 35 J/cm2 at temperature -70°C in new sparingly alloyed cold-resistant steel. The effect of various quenching and tempering parameters on mechanical properties, structure of steel and fracture mode of samples after impact tests at temperature -70°C has been studied. The interaction between the properties, structure and fracture mode of steel samples are shown. The optimal heat treatment parameters of new sparingly alloyed cold-resistant steel are determined.

Keywords: sparingly alloyed high-strength steel, cold resistance, reduction of carbon equivalent, scanning electron microscopy, transmission electron microscopy, mechanical properties, structure, bainite, martensite, quenching, tempering.

Design of polymeric materials on the molecular principles. II. The molecular mobility in the cross-linked complex systems

Analysis of scientific and technical data and previously studies of the dynamic mechanical properties of semi- interpenetrating polymer networks (semi-IPN) showed that the change in the temperature position of the relaxation transitions in the network can result from blocking strong intermolecular bonds between the nodal fragments of the network by the linear component , or, on the contrary, the formation of additional strong intermolecular bonds between the nodes of the polymer network by the linear component. The carried out analysis confirms the observed peculiarities of the relaxation behavior of semi-IPN based on cross-linked polysiloxanurethanes and linear polymethylmethacrylate.

Keywords: dynamic mechanical analysis, glass transition, mechanical loss tangent, polysiloxaneurethane networks, interpenetrating polymer networks (IPN), semi-IPN.

Differential vacuum molding as an advanced technology of vacuum molding

Autoclave moulding is the traditional method of manufacturing high quality polymer composite materials (PCM). Striving of manufacturers to make cheaper the production leads to the active development of out-of-autoclave moulding technologies. The most simple and famous technology is vacuum moulding. Differential moulding (or Double Vacuum Bag moulding) is an advanced form of vacuum moulding which allows avoiding drawbacks of the last one.

Systems of paint coatings for helicopter equipment

The present paper describes the results of study on increase of weather resistance of systems coatings with epoxy-polyamide enamels, including their repair and repainting without removal of an old coating. The influence of light stabilizers, which either absorb UV-radiation from a certain part of the spectrum, or prevent oxidative degradation in the coating based on enamel EP-140 is studied. According to the results of the research, protective systems of paint coatings have been developed, including primers and enamels VE-46 for helicopters, resistant to weathering and pouring aggressive liquids. The developed coating systems with enamels VE-46 and KO-5189 have increased thermal stability at temperatures up to 350°C and high resistance to synthetic and mineral oils, aviation fuel and gasoline.

Keywords: paint coatings, corrosion, helicopters, repair technology, polymer composite materials.

Polymeric compositions for protection against contact corrosion

In work operational properties of coatings on the basis of protective polymeric compositions VP-1 and VZP-1- adhesive, physical and mechanical properties in initial condition and after artificial aging are researched. The kinetics of fuel swelling capacity and moisture absorption of coatings in initial condition and after artificial aging is studied. Adhesive and physical and mechanical properties of coatings after long (during 2000 h) tests in fuel and water are defined. The structurally similar samples simulating contact of diverse materials «aluminum alloy-carbon fiber reinforced plastic» and also fixing elements are produced. Protective properties of VZP-1 composition on the structurally similar samples made of diverse materials (aluminum-carbon fiber reinforced plastic), including fixing connections after tests in salt spray chamber (KST) during 3000 h are researched. It is established that protective polymeric compositions VZP-1 and VP-1 possess high adhesive, physical and mechanical properties, fuel - and water resistance, protective properties and can be used to protect contact joints of diverse materials and fixing connections.

Keywords: polymeric corrosion-resistant compound, epoxy oligomer, corrosion resistance, moisture resistance, adhesion, modifier, hardener.

Modeling of moisture saturation in polymer composites in real climatic environmental conditions

The moisture saturation in polymer composites is numerically modelled using Fick ¢ s equations for the service life of an aircraft. Temperature changes and air humidity are taken into account in real climatic environmental conditions. It has been obtained good matching of calculations and experimental data for moisture saturation during the year. It is numerically shown that solar heating and exploitation greatly affect on the level of moisture. On the other hand, effect of prolonged external loads failed to be significant.

Keywords: carbon fiber reinforced plastics, environmental testing, climatic conditions, relative humidity.

Difficulties of the transition to quantitative estimation of fracture energy intensity at drop-weight tear tests of specimens in full thickness

Drop-weight tear test (DWTT) is widely applied in pipe industry to examine the acceptance properties. Test conditions are close to the fracture condition of structures however a quantitative criterion is needed for modern materials. The reliability of existing empirical assessments as well as the possibility to determine the crack initiation and propagation components of the fracture energy are considered. A correlation between specimen fracture energy and crack tip opening angle (CTOA) is substantiated.

Keywords: drop-weight tear test, crack initiation and propagation, CTOA.
