Shashkova L.V. FRAGMENTATION OF 20 STEEL PERLITE AT NONSTATIONARY DIFFUSION OF HYDROGEN [№ 6 ' 2007] The phenomenon of 20 steel perlite observed at hydrogenation is described in this article. The method of electron microscopy for studying of metal defective structure transformation is used here. It is shown that the reason of the phenomenon is a relaxation of concentration hydrogenous microstress. Observed phenomenon of perlite fragmentation is accommodative process of repeated type and is observed at room temperature on the stage of disbalance diffusion of hydrogen.
Savchenko E.A., Shashkova L.V., Manakov N.A. SYNERGETIC CONCEPTION OF HYDROGEN DAMAGEABILITY OF METALS AND METALS (STAGES OF DEVELOPMENT AND PERSPECTIVES) [№ 1 ' 2006] 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., Shashkova V.K., Shashkova L.V. DISSIPATIVE TRANSFORMATIONS OF THIN STEEL`S MICROSTRUCTURES IN CONDITIONS HYDROGEN`S DIFFUSIVE TRANSFER [№ 10 ' 2005] 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.
