TL;DR: In this paper, the authors studied the impact toughness of 12Cr1MoV steel Charpy specimens at the temperature range from 20°C to 600°C and revealed that the increase of the testing temperature from 20ºC to 375ºC and then to 600ºC causes impact toughness to decrease by 1.2 and 2.42 times respectively.

TL;DR: In this paper, the authors provided new experimental data for high-strength VT 22 titanium α+β-type alloy under impact-oscillatory loading and dynamic non-equilibrium process.
Abstract: The purpose of this paper is to provide new experimental data for high-strength VT 22 titanium α + β-type alloy under impact-oscillatory loading and dynamic non-equilibrium process. Based on the performed experimental studies, it was found that overall plastic deformation of this alloy can be increased by a factor 2.75 compared with its initial state without significant loss of strength. To achieve this goal, a new methodology to study the impact behaviour of materials under non-equilibrium process has been used. Physical research revealed that significant microstructural refinement of the alloy is observed after such type of loading, as the result of which the fine grains are formed with subgrain refinement which takes place within the basis of alloy.

TL;DR: In this article, a Fractographic analysis of failure mechanisms of steel 17G1S cut in the length and breadth of the pipe is implemented, which can serve as confirmation of the increase in hardness and microhardness.
Abstract: Mechanical properties are substantiated, that are the most vulnerable to maintenance material deterioration of under prolonged operating time, accompanied by intense damage. The opposite behavior of relative elongation and contraction indicates the intensity of scattered damage of the operated metal. Reducing the percentage reduction indicates operational metal embrittlement, as a result of strain hardening, which can serve as confirmation of the increase in hardness and microhardness. Fractographic analysis of failure mechanisms of steel 17G1S cut in the length and breadth of the pipe is implemented.

TL;DR: In this article, the areas of low frequency and corrosion fatigue for basic metal and welding joints of oil and gas pipelines have been determined on the basis of corrosion-fatigue test results.
Abstract: The areas of low frequency and corrosion fatigue for basic metal and welding joints of oil and gas pipelines have been determined on the basis of corrosion-fatigue test results. The most dangerous diapasons of the operation loadings were also determined. The present work also proposes the methodical approaches to the survivability prediction.

TL;DR: In this paper, the impact toughness of 12Cr1MoV steel Charpy specimens has been studied in the range of temperatures from 20°C to 600°C, and it was found that ion beam treatment of steel deteriorates impact toughness at the tested temperatures by 5-42%.
