Savchenko E.A. PARAMETER OF DAMAGEABILITY AND CLUSTER MECHANISM OF STEEL HYDROGEN BRITTLENESS The cluster mechanism peculiarities of brittle destruction of the system: steel – hydrogen in conditions of transient diffusion of chemical impurity are researched on the base of law of hydrogen damageability. It was distinguished that metal-hydrogen clusters are slim disks with diameter from five to forty Angstroem units. Pictures of clusters zones on steel breakings at abruption and pure shear were got. The analysis of existing conceptions of chemical impurity introduction clusterization was done here. The new results are basis of dynamic active conditions of metal-hydrogen clusters with hyperelastic features.
Savchenko E.A., Shashkova L.V., Manakov N.A. SYNERGETIC CONCEPTION OF HYDROGEN DAMAGEABILITY OF METALS AND METALS (STAGES OF DEVELOPMENT AND PERSPECTIVES) It is shown in the article that synergetic approach to the phenomenon of hydrogen materials fragility, originated at the contact with damp hydric sulphide gas, allowed getting original scientific results, working out theory of hydrogen fragility and solving actual practical tasks of diagnostics and increase of steel hydrogen resistance. A new concept of fractal energy hierarchy of structural material conditions, which has an applied and fundamental meaning and opens opportunities of energy parameterization of microstructures were introduced in physics of durability and materials science.
Savchenkov E.A., Aytkulov P.P. CORROSION PROPERTIES OF STEEL WITH CELLULAR-POLYGONAL SUBSTRUCTURE It is experimentally established that the two-level cellular-polygonal substructure received on technology of explosive hardening and thermal processing, in one and a half – three times improves parameters of corrosion resistance and water resistance of steel in hydrogen-sulphidous medium. The mechanism of increase of thermodynamic stability of metal is discussed.
Savchenkov E.A., Shashkova V.K., Shashkova L.V. DISSIPATIVE TRANSFORMATIONS OF THIN STEEL`S MICROSTRUCTURES IN CONDITIONS HYDROGEN`S DIFFUSIVE TRANSFER The article is devoted to researches of open system steel - hydrogen in conditions of diffusive transfer of an embedding impurity. The method of x-ray diffraction in situ is used during electrochemical hydrogenation of membranes and electronic microscopy for studying transformations of defective metal structure. Repeatability of processes of accumulation and discharge of micropressure with reorganization of defective structure in ОКР are established, migration of borders, formation of deformation relief, a substructure and porosity are also examined. The initial structure of steel influences on the kinetics of transformations.
Savchenkov E.A. DESTRUCTION ENERGIES STRUCTURE FRACTAL SPECTRUM BY DIFFUSION ACTIVATED HYDROGEN STEAL Synergism of steal-hydrogen system is studied on basis of hydrogen damaging law. Structure break energy fractal spectrum is disclosed with level self-similarity function. The M factor is changing under geometric progression law and a constant, - universal dimensionless complex of material fundamental characteristics controlling stability of crystal array, is energetic spectrum quantum. Possibility of energetic parametrization of structure is disclosed. Ideas of energetic conditions of steal structures are introduced to Durability Physics and Hylology.
