“…Among the most used techniques to analyze the metallographic microstructure are optical (OM), scanning electron (SEM), and transmission electron (TEM) microscopy [19,31,32]. Other aspects, such as the grain boundary misorientation and the crystallographic size, can be quantified through the Electron Backscatter Diffraction (EBSD) technique [3,4,11,16,33,34]. On the other hand, when it is required to know the elemental composition, Energy Dispersive Spectroscopy (EDS) or the Optical Emission Spectrometer (OES) are used [2,12,13,18,32,[35][36][37][38][39][40].…”

“…As can be seen, there is a clear understanding in the literature of Nb effects on steel mechanical properties. However, there are still gaps in knowledge regarding the impact and potential of Nb addition on the corrosion resistance of microalloyed steels [16]. Some studies show that small Nb additions can improve steel corrosion resistance in different environments.…”

Steel structures are prone to corrosion, a chemical reaction between steel and the atmosphere that gradually weakens the material. Over time, this reaction can significantly reduce the structural integrity and lifespan of steel elements. Without intervention, corrosion can cause structures to fail, leading to financial, environmental, and potential human losses. Enhancing steel’s corrosion resistance is crucial, and one method involves adding niobium (Nb). Niobium microalloyed steels are known for their increased strength, and some research indicates that Nb may also improve corrosion resistance by making the grain structure of the steel finer. However, the complete potential of Nb in corrosion prevention remains underexplored, with significant research gaps across various scales, from microstructural impacts on durability to macroscopic effects on mechanical properties. The research community has utilized numerous experimental approaches to test corrosion resistance under different conditions, but there is a lack of comprehensive studies that aggregate and analyze these findings. This paper seeks to fill that void by reviewing the impact of Nb on the strength and corrosion resistance of structural steels, examining how steel beams’ ultimate capacity degrades over time and identifying key areas where further research is needed to understand Nb’s role in mitigating corrosion.

“…On the other hand, corrosion is also a crucial factor affecting the safety of equipment and facilities in the exploration, extraction, transportation, and refining processes of oil and gas [8][9][10][11]. The environment of oil and gas fields is complex and harsh, often characterized by high temperature, high pressure, high salinity, and high mineralization.…”

A series of advanced equipment exposed to sub-/supercritical water environments at high temperatures, high pressures, and extreme water chemistry with high salt and dissolved oxygen content faces serious corrosion problems. Obtaining on-site corrosion data for typical materials in harsh environments is crucial for operating and maintaining related equipment and optimizing various corrosion prediction models. First, this article introduces the advantages and disadvantages, usage scenarios, and future development potential of several in situ monitoring technologies, including ultrasonic thickness measurement, the infrared thermography method, microwave imaging, eddy current detection, and acoustic emission. Considering the importance of electrochemical corrosion data in revealing microscale and nanoscale corrosion mechanisms, in situ testing techniques such as electrical resistance probes, electrochemical corrosion potential, electrochemical impedance spectroscopy, and electrochemical noise that can be applied to sub-/supercritical water systems were systematically discussed. The testing platform and typical data obtained were discussed with thick and heavy colors to establish a mechanical prediction model for corrosion behavior. It is of great significance to promote the development of corrosion monitoring techniques, such as breaking through testing temperature limitations and broadening the industrial application scenarios and maturity.

“… 6,7 Acid corrosion was first reported in a Texas well in 1940, and since then, it has remained a persistent issue in various oil fields worldwide. 8,9 In the oil and gas industry, over 950 000 wells are characterized as acidic, constituting approximately one-third of all wells. 10 Moreover, water drive is commonly employed in the development of gas fields to enhance their economic benefits.…”
