mLife, Volume 1, Issue 1, Page 13-20, March 2022., 2022 Abstract Corrosion of iron‐containing metals under sulfate‐reducing conditions is an economically important problem. Microbial strains now known as Desulfovibrio vulgaris served as the model microbes in many of the foundational studies that developed existing models for the corrosion of iron‐containing metals under sulfate‐reducing conditions. Proposed

Elimination and Control of δ Ferrite in M50NiL Bearing Steel
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 In this study, the effects of the annealing temperature and holding time on the δ ferrite content in M50NiL bearing steel are evaluated. The results indicate that when the temperature increases from 900°C to 1200°C, the δ ferrite content increases as a result of the increase in the Cr equivalent in the matrix, which decreases the stability of austenite

Thermodynamic analysis of X80 pipeline steel after calcium treatment [PDF]
Proceedings of the 2015 2nd International Conference on Machinery, Materials Engineering, Chemical Engineering and Biotechnology, 2016 Based on thermodynamic calculation, analysis the inclusions and thermodynamics of X80 before and after calcium treatment on the sample of a steel production.Results show that the effect of Al2O3 inclusions degeneration is good and S would exist in a dissolved state so that avoids the CaS inclusion precipitation when the ω(Als) is 0.04%,ω(O) is adjusted

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 Long‐distance pipelines are threatened by a variety of natural geological hazards. A stress monitoring system driven by the strain‐stress solution algorithm was proposed; it can achieve real‐time maximum axial stress measurement by installing vibrating wire gauges (VWGs) on the surface of the pipe.
