Summary: The SCC behavior of X80 pipeline steel was studied under the conditions of D. desulfurican, AC interference, and cathodic protection. The results showed that both AC interference and negative CP potential aggravated pitting corrosion and enhanced the SCC susceptibility under constant load. In the saline soil environment containing D. desulfurican, AC greatly contributed to the cracking tendency of X80 pipeline steel, resulting in a narrow safe CP range for practical engineering application, requiring appropriate discharge methods.

Summary: This study investigated the inhibition of corrosion of deposit-covered pipeline steel in seawater containing CO2 in the presence of Pseudomonas stutzeri. The results showed that the presence of deposits led to a decline in the corrosion rates of the steel, and the corrosion rates were slower when P. stutzeri was present. The corrosion inhibition efficiency of P. stutzeri was reduced in the presence of deposits, likely due to the lowered biological activity.

Summary: The corrosion behavior of X80 pipeline steel welded joints by sulfate-reducing bacteria (SRB) has been explored. It was observed that in the sterile medium, the heating affected zone (HAZ) showed larger and deeper corrosion pits compared to the base metal (BM) and weld zone (WZ). However, in the inoculated medium, Desulfovibrio desulfuricans (D. desulfuricans) primarily attached to the BM and WZ, increasing their local corrosion sensitivity. D. desulfuricans showed a dislike for attaching to the HAZ surface, leading to non-uniform corrosion dominating the surface.

Summary: The study revealed that the corrosion resistance of different sub-regions in the heat-affected zones of X80 pipeline steel is influenced by their microstructural sensitivity to CO2 corrosion in NaCl aqueous solutions. The weakening of corrosion resistance in the coarse-grained HAZ is attributed to larger grain size and coarsening martensite/austenite constituents in the matrix.

Summary: The study found that a liquid film with a thickness greater than or equal to 1 mm has no effect on the mechanism of the corrosion process, but has a control effect on the corrosion rate and the time of each stage in corrosion. The corrosion process can be divided into two stages: in the early stage, the concentration of ions inside and outside ADP is the same, so the corrosion is uniform; in the later stage, due to the influence of CO2 dissolution and mass transfer distance, the cathodic reaction is mainly outside ADP and the anodic reaction is mainly inside ADP. In addition, corrosion acidification occurs in ADP, which enhances the corrosion process in ADP.

Summary: This study systematically investigated the effect of Pseudomonas sp. on the static tidal corrosion of X80 pipeline steel using various analytical techniques. The results showed that the sessile Pseudomonas sp. count multiplied with the increase in elevation after 720 hours of exposure. The corrosion of the steel in the inoculated environment was mainly localized, with an increase in corrosion rate, pit depth, and corrosion product thickness due to the higher bacteria number. Pseudomonas sp. significantly accelerated both uniform and localized corrosion of the steel in the marine tidal zone, with the acceleration role enhancing with the steel elevation in the tidal zones.

Summary: This study investigates the local corrosion behavior of X80 steel welded joints in a CO2-saturated NACE solution under different flow rates. It is found that the heat-affected zone (HAZ) exhibits the worst corrosion resistance, while the base metal (BM) and weld metal (WM) show similar corrosion resistances. The HAZ acts as an anode and the enhanced wall shear stresses promote the development of local corrosion. This research provides scientific guidelines for the corrosion protection of long-distance oil & gas pipelines.

Summary: The study investigated the hot deformation mechanisms, mechanical properties, and microstructural evolution of a HP-Nb steel used in reformers tubes for oil and gas industries. Results showed that increasing temperature reduced flow stress and increasing strain rate offset this effect. Dynamic recrystallization was observed at 800°C and 1000°C, leading to increased ductility. Increasing deformation temperature to 900°C decreased the possibility of dynamic recrystallization, primarily due to strain-induced precipitation and solute drag of Nb element.

Summary: The harsh operating environment and extreme working conditions of steam turbine blades have led to the use of alloys with special characteristics, such as high corrosion resistance and excellent rupture strength. The presence of foreign particles and fuel impurities in the turbine environment has caused damage to the blade through erosion and corrosion mechanisms, ultimately leading to the formation of fatigue cracks and reducing the fatigue strength of the blade. Consequently, it is predicted that the reduced fatigue strength will result in a shortened service life for the blade.

Summary: Increasing the Al content in the Fe-14%Mn-1.05%C steel led to larger austenite grain size, reduced carbide precipitation, higher yield strength, hardness, and wear resistance but lower tensile strength, ductility, and energy absorption capability. Wear mechanism was identified as abrasive wear in the form of parallel grooves on the worn surfaces. Additionally, increasing Al content decreased friction coefficient, weight loss, and surface damage.

Summary: Chemical Vapor Deposition (CVD) is a process where a solid is formed on a substrate through chemical reactions in the vapor phase. It allows for the coating of various materials, such as ceramic nanocomposites, dielectrics, and single crystalline silicon, onto different substrates. The design of a CVD system is influenced by factors like substrate dimensions, temperature, chemical composition, deposition process, chamber temperature, material purity, and production economics. Surface reaction kinetics, mass transfer reactions, and desorption reactions are involved in the CVD process. Thermodynamically, CVD requires high temperatures and low pressures. Kinetic control is used at low temperatures, while diffusion control is applied at high temperatures. Coatings in CVD are typically deposited at temperatures ranging from 900 to 1400 degrees Celsius. By controlling chamber temperature, precursor purity, and precursor flow rate, it is possible to partially control deposition rate and microstructure of ceramic coatings during the CVD process.

Summary: This study investigates the impact of HVOF coatings of Inconel, aluminum, and Colmonoy on the corrosion resistance of stainless steel substrates. Characterization of the coated samples was carried out using SEM, XRD, and EDS techniques. Impedance and Tafel tests were conducted to analyze the corrosion responses of the coatings at different temperatures. Inconel-coated specimens exhibited superior corrosion behavior due to the formation of Cr2O3 layers, which prevented chloride ions from diffusing across the coating. Although the Al-coated sample showed oxide layer formation according to the Nyquist curve, the Tafel test results indicated severe corrosion.

Summary: This study investigates the microstructure and mechanical properties of mechanically alloyed and spark plasma sintered AlCoFeMnNi-xB (x = 0, 0.5, 1, and 5 at. %) high-entropy alloys (HEAs). Boron-doped HEAs were synthesized using mechanical alloying and consolidated using spark plasma sintering. The microstructural evolution and phase differentiation were analyzed using scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. The mechanical properties were evaluated using shear-punch test, and the fracture surface was studied using SEM. The correlation between microstructure and mechanical characteristics of the boron-containing high-entropy alloys is discussed.
