“…In quasi-static tests, the moving gripper travel speed was 0.4 mm/min. The registration of strain localization patterns by digital image correlation (DIC) was performed simultaneously with stretching [22][23][24][25][26]. The method of digital image correlation (DIC) was carried out using a PL-B781F video camera (Pixelink, Canada) with illumination of the working part with an SNF-xxx-635-30-KB laser.…”

“…Currently, the issues of assessing creep in heat-resistant steels used in thermal power engineering are occupied not only by legal organizations, but also by research teams led by such scientists as Khazhinsky G.M., Lokoshchenko A.M., Botvina L.R., Makhutov N. A. and others [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. In particular, they consider the issues of not only directly conducting long-term tests, but also the development of software products that are close to real processes that occur with the material during long-term operation.…”

The use of acoustic and magnetic methods of non-destructive testing to detect zones of stable localization of deformation in order to assess and predict the performance of long-term equipment is of scientific and practical interest at present. A structural-mechanical criterion has been developed, that reflects the revealed relationships between the structural and substructural states, internal stress fields and stable localization of deformations with the characteristics of non-destructive tests in the metal of long-term equipment made of structural 0.2 С steel and heat-resistant 0,12C-1Cr-1Mo-1V steel. The values of the structural-mechanical criteria Ks.-m for structural 0.2 С steel and for heat-resistant 0,12C-1Cr-1Mo-1V steel, corresponding to the moment of stable localization of deformation, are established. At the same time, it is recommended to replace the checked equipment nodes due to the exhaustion of the resource. The proposed and justified approach to assessing and predicting the performance and residual life of long-term power equipment, based on the identified relationships between the structural and substructural states, internal stress fields and stable localization of deformations with the characteristics of non-destructive tests and the calculation of the structural-mechanical criterion, was applied at a number of power plants in the Kemerovo region – Kuzbass. A methodology has been developed for evaluating the residual life, based on the identification and use of relationships between structural and substructural states, internal stress fields and stable localization of deformations with the characteristics of non-destructive tests and the calculation of a structural-mechanical criterion.
