STUDY OF A HIGH-TEMPERATURE INTERMETALLIDE MATRIX OF THE Ni–Al–Co SYSTEM FOR PRODUCING STRUCTURAL ALLOYS WITH INCREASED PLASTICITY (review)

A generalization of the results of scientific and technical publications is presented, the analysis of which will allow to develop scientific foundations for the creation of a new class of heat-resistant structural materials based on intermetallic matrices with increased plasticity at room temperature and high specific strength at temperatures up to 950 °C in the Ni–Al–Co system. It is shown that alloys of the Ni–Al–Co system can be used in the manufacture of rotary parts in the form of gas turbine engine discs (GTE), working at temperatures up to 950 °C, as well as materials for GTE blades due to heat resistance at temperatures up to 1200 °C.

MODERN MATERIALS FOR THE AIRCRAFT CABIN

The paper considers the latest technologies and polymer composite materials developed at FSUE «VIAM» and used in the manufacture of structural elements of a passenger aircraft cabin (namely: air conditioning systems, three-layer interior and floor panels) that meet the requirements of the Aviation Regulations AP-25 (Appendix F, Part I ), as well as the requirements for mechanical and mass characteristics. The developed products are made entirely from domestic components, which in turn reduces dependence on imported materials.

FEATURES OF THE MAGNETIC STATE IN AMORPHOUS RE–TM AND RE–TM–B MAGNETS (review)

Provides an overview of the magnetism features of amorphous magnets of the RE–TM and RE–TM–B alloys (RE – rare earth metal, TM – transition metal, B – boron). Magnetic states in amorphous alloys, the effect of the single-ionic anisotropy of heavy rare-earth metals on local disorder and spin frustrations in an amorphous body, and some spin-reorientation transitions observed in such compounds are presented. It is shown that the identification of the spin-glass state can be achieved by detecting specific features on the field and temperature dependences of the magnetic moment and magnetic susceptibility of the sample.

RESEARCH OF ADHESION AND ADHESIVE DURABILITY OF FUNCTIONAL PAINT COATINGS FOR PROTECTION OF POLIMER COMPOSITE SURFACE

Adhesion and adhesive durability of functional systems of paint coatings on the basis of epoxy resin primer and polyurethane enamels to surfaces of polymeric composite materials with different geometrical and qualitative characteristics of surface on the basis of the epoxy binding are investigated. It is shown that the significant contribution to durability of coupling of film of paint coating in addition to mechanical forces is brought by also chemical nature of two components of adhesive interaction.

FEATURES OF DESTRUCTION OF NITRIDED SAMPLES OF 38H2MYuA AND 30H3MA STEELS

The article deals with the features of deformation and destruction of samples that have undergone chemical-thermal treatment, using the example of testing nitrided samples of steels 38H2MYuA and 30H3MA. It is established that the mechanical properties determined during the tensile testing of samples with a highly rigid brittle layer cannot serve as design characteristics when evaluating the bearing capacity of parts that have undergone chemical-thermal treatment. Testing of nitrided samples of 38H2MYuA and 30H3MA steels demonstrated a complex process of their deformation and destruction, and the test result showed that this steel treated to the «hardened + high tempering» mode sensitivity to the most dangerous concentration the crack is absent.

The work carried out studies of the physicomechanical properties of polysulfide sealants of brands of U-30M and UT-31 after thermal, light aging, and the assessment of mushrooms. The data on the resistance of sealants of brands U-30M and UT-31 are investigated and summarized after the impact of accelerated climatic tests and aggressive environments. The optimal time and conditions for the storage of vulcanized sealants in the unattended state and components of sealants in warehouse conditions are determined, as well as the causes of different storage of sealing pastes based on liquid thiocola.

DESTRUCTIVE METHODS FOR DETERMINING RESIDUAL STRESSES (review)

The paper presents an overview of methods for determining residual stresses. Methods such as splitting and segmentation, layer-by-layer removal, slitting (cutting, pliability), profiling, drilling holes (including a «deep» hole) are considered. The description of the methods for mea-suring the deformation used in the determination of residual stresses is given. The most common contact method using strain gauges, as well as non-contact methods: polarization-optical (photo-elasticity), optical speckle interferometry, digital image correlation.

STUDY OF THE PLASTICIZING EFFECT OF MOISTURE ON THE PROPERTIES OF VSE-34 BINDER BASED PCMS AFTER 5 YEARS EXPOSURE IN THE DIFFERENT CLIMATE ZONES

The plasticizing effect of moisture on the glass transition temperature of VSE-34 solvent-free epoxy binder based polymer composite materials (PCMs) with different reinforcement was studied. Natural weathering was performed in three climatic regions of Russia: Moscow, Gelendzhik, Sochi. It was shown that the glass transition temperature is significantly reduced after 1 year of exposure and then is gradually increased after 3 and 5 years of exposure. Samples were studied in «as-received» state as well as after drying and saturation by water till mass stabilization in order to investigate the moisture influence on PCMs’ glass transition temperature. Linear relationship between glass transition temperature and moisture content was observed.

MODERN APPROACHES TO ASSESSING THE IMPACT OF EXTERNAL FACTORS ON MATERIALS AND COMPLEX TECHNICAL SYSTEMS (to the 120th anniversary of G.V. Akimov)

The founder of the science of protecting materials from corrosion, aging and bio-damage in Soviet Russia is Georgy Vladimirovich Akimov, who created the infrastructure for climate testing of materials and products. Currently, his students and followers have discovered new directions for the development of climatic and microbiological tests – these are studies of the preservation of the properties of materials in complex technical systems under the influence of climatic factors, mold fungi, bacteria and operational loads using the most modern methods at the sites of the created network of climate test stations, as well as using modern regulatory documentation.
