TL;DR: In this article, the effect of hydrogen absorbed by metal on the variation of the structure and mechanical properties of the main gas pipeline after a long-term operation is found. But the main regularities in the graded nature of the static deformation process and the impact of hydrogenation on the scattered damage and fracture accumulation are found.

TL;DR: In this article, the fractographic analysis of the pipe surface of a distribution gas pipeline after 40 and 56 years of operation is performed. And the mechanisms of formation of corrosion pits, laminations, and deep crack-like defects are systematized.

TL;DR: In this article, the stage-like nature of the fatigue crack propagation in the bimetallic specimen into macro-, meso-, and micro-levels was determined. But the authors did not consider the effect of the bimodal material on the fatigue cracks.

TL;DR: In this article, the basic regularities of biocorrosion processes in the 17G1S-U pipe steel under the influence of Desulfovibrio Sp. strains Kyiv-10 was obtained by weight-loss testing and surface analysis techniques.

TL;DR: In this article, a pseudostereopair is used to determine the geometry of the start zone of the brittle separation crack in OSL steel and the stretch zone of railway axis steel.
