Plasticity characteristics defined on axial samples also were insensitive to changes in the technical state of the metal different zones perish from operation . While the characteristics of plasticity, defined on the tangential samples confirmed the feasibility of decommissioning perish , since the narrowing of the spread of the metal band is dying 2 times lower than the minimum acceptable (27% and 55 % respectively). Evaluation of the ratio of the metal boundary fluidity and strength of metal with the corresponding zones perish also confirmed the conclusion that the metal is stretched zone dying pipi power station does not satisfy the requirements of regulatory documents . The rapid decrease in toughness of metal stretched zone dying pipe obtained on samples of both orientations, to a level that does not meet the requirements for heat-resistant steels , confirmed that the characteristics of brittle fracture resistance are highly sensitive to changes in the technical state of the metal pipe particular exhibit differences as metal different zones perish . An approach to the classification fractografic image breaks through the spectrum of generalized fractal dimensions Rainier . Established that the proposed approach makes it possible to classify the studied image Chebyshev minimum distance . In analyzing fractohrafic images please note that the spectrum of generalized fractal dimensions Rainier is sensitive to the scale , intensity and rotation. This aspect can also be used when assessing texture images . Signs generated from the quantitative characteristics of point images, which are based on images of fracture surface of the material, allow the selection of homogeneous areas in the image that correspond to a particular mechanism of destruction. A method to determine the epicenter of the mirror component on real images of the surface. It is possible to more accurately estimate normal field , which increased the accuracy of the reconstruction on average by 10%.
