"The state of residual stresses on smooth bends fabricated by electric induction heating of thick-walled tubes will be determined in the project. A combination of present-day renowned methods - the hole-drilling method and the roentgen rays diffraction - will be utilized for such determination. Thus, the necessity of consequent high-priced operations, which are enforced by some older domestic standards, will be expertly considered on the basis of acquired data. More precisely, it will be directly aimed at a check of objective requirement on annealing operations and together with it connected rehabilitation of a bend surface (because of scaling and geometric deviations). The specimens of bends designated for tests will be chosen from a spectrum of dimensions and materials and will be manufactured by a renowned technology. The obtained data will be available for expert community and base data for computer modeling of residual stresses state during the production of bend will be available as well,"@en .
