Summary: The stress corrosion behavior of X70 pipeline steel under the combined action of SRB and constant load was investigated. It was found that plastic stress and SRB greatly increased the susceptibility of X70 pipeline steel to stress corrosion cracking (SCC). SRB promoted pitting corrosion, and the synergistic effect of SRB and plastic stress further enhanced the occurrence of pitting on the pipeline steel. Elastic stress did not play a significant role in promoting corrosion. The synergistic effect of tensile stress and SRB was explained from the perspective of corrosion thermodynamics.

Summary: The behavior and mechanisms of stress-assisted microbiologically influenced corrosion (MIC) of X80 pipeline steel induced by sulfate-reducing bacteria (SRB) were studied using focused ion beam-scanning electron microscopy (FIB). Electrochemical results demonstrated a synergistic effect between SRB and stress on the corrosion of X80 steel. SRB accelerated the transformation of Fe3O4 into iron-sulfur compounds and may have caused film breakage in X80 steel products. FIB results provided direct evidence of SRB promoting the corrosion of X80 steel.

Summary: In this study, a silicone-modified epoxy coating was designed to reduce sulfate-reducing bacteria (SRB)-induced corrosion. The modified coating exhibited better protective effect against acid- and SRB-induced corrosion, higher corrosion resistance, and improved thermal stability compared to the pure epoxy resin coating. The results demonstrate that the silicone-modified epoxy coating has good MIC resistance and can be used as a protective coating for susceptible iron-based materials in industries such as marine engineering and oil exploration.

Summary: The corrosion behavior of the heat affected zone of X80 pipeline steel was studied in coastal saline soil with or without sulfate-reducing bacteria (SRB). In the sterile soil environment, corrosion pits detected in the coarse grain zone (CGZ) were larger in size and higher in density compared to those in the fine-grained zone (FGZ) and fusion zone (FZ). In the presence of SRB, the microbes increased the corrosion of FGZ, CGZ, and FZ, with CGZ coupons exhibiting higher susceptibility to corrosion.

Summary: This study explores the impact of hydrophobic subunit and chain length variation on the antibacterial and antibiofilm activity of beta-peptide polymers. The results demonstrate that the optimal beta-peptide polymer has low toxicity towards host cells and exhibits excellent antibacterial activity and antibiofilm formation ability against Cariogenic Streptococcus mutans. Additionally, beta-peptide polymers decrease the hydrophobicity of bacterial cells and promote biofilm dispersion. Transcriptome analysis reveals that beta-peptide polymers reduce the cariogenicity of S. mutans by impacting the transcription of energy and acid metabolism-related genes.

Summary: In this study, high-entropy alloy nanoparticles with excellent photothermal heating properties were synthesized. Through the synergistic effect of copper ion release and thermal damage, more reactive oxygen species were generated, leading to the disruption of cell membranes and elimination of biofilms. Under solar irradiation for 30 minutes, the antibiofilm efficiency of the high-entropy alloy nanoparticles improved from 81% to 97.4% in marine nutrient medium. This research demonstrates a new strategy for effectively treating marine microorganisms using high-entropy alloy nanoparticles with photothermal heating characteristics as antibacterial agents.

Summary: In this review, the mechanisms of metal corrosion caused by microorganisms are examined and different strategies to prevent it are explored. The high diversity of microorganisms, typically forming biofilms, has been implicated in corrosion, which is a multi-trillion dollar problem annually. While aerobic microorganisms establish conditions that promote metal corrosion, anaerobes are mainly responsible for corrosion. Microbially produced organic acids, sulfide, and extracellular hydrogenases can accelerate the oxidation of metallic iron (Fe-0) coupled with hydrogen (H-2) production, as can anaerobic microorganisms using H-2 as an electron donor. Some bacteria and archaea directly accept electrons from Fe-0 through c-type cytochromes as an apparent outer-surface electrical contact with the metal. Functional genetic studies and omics studies are providing a better understanding of corrosion mechanisms and the microorganisms involved. Interdisciplinary studies on the interactions between microorganisms and metals in corrosive biofilms offer potential for developing technologies to detect and prevent corrosion.

Summary: This study compares the fatigue behavior of bcc Nb-48 wt%Ti (Ti-36at%Nb) alloy parts processed by Laser Powder Bed Fusion (L-PBF) using two different types of powders (spherical powder produced by Plasma Atomization and irregularly shaped powder produced by Hydride-Dehydride). The results show that the fatigue behavior is similar for both powders, but the specimens produced from the Hydride-Dehydride powder have higher dispersed results. Fracture primarily occurs in the porosities near the machined sample surface, and the fatigue cracks propagate in a zigzag mode parallel to the L-PBF building direction.

Summary: During a major overhaul of an aeroengine, a cracked stator vane of the low-pressure compressor was discovered, with the crack originating from a corrosion pit located on the arc transition between the leading edge and the upper edge plate. The fracture surface exhibited signs of fatigue cracks, indicating a pit-related fatigue crack. Metallographic examination revealed that most corrosion pits were distributed beneath the bulging or peeling paint layer on the leading edge and the concave side. Identification of the corrosion products showed the presence of sulfate and alumina, suggesting atmospheric corrosion as a likely cause for the cracked stator vane.

Summary: Tube-to-tube impact wear is a significant factor in the failure of alloy 690 tubes in nuclear steam generators. This paper investigates the wear damage mechanism and detection method of alloy 690 tubes under tube-to-tube impact loads. The results reveal the wear damage mechanism through analysis of macro and micro morphologies as well as metallographic structures. A nonlinear ultrasonic wave mixing method is proposed for damage detection and a detection device is developed to implement this method. Experimental results indicate that the damage mode of tube-to-tube impact wear varies with impact load and cycle number, and the nonlinear modulation index is effective in assessing the damage degree of alloy 690 tubes.
