A study of metal samples from exploited and damaged sections of steam pipelines made of 0.12С-1Сr-1Mo-1V steel after deformation to the formation of zones of stable localization of deformations by the method of electron microscopy was carried out. Specimens without exploitation, after exploitation, but not damaged, and specimens after exploitation before destruction were investigated. As a result of the studies carried out for each sample, the phase composition was determined (qualitatively and quantitatively), and the following parameters of the fine structure were calculated: volume fractions of structural components of steel, scalar ρ and excess ρ± dislocation density, curvature-torsion of the crystal lattice χ, amplitude of internal stresses (shear stress and long-range stresses). All quantitative parameters of the fine structure are determined both in each structural component of steel, and in general for each sample. [ABSTRACT FROM AUTHOR] |
