Summary: The corrosion behavior of Cu-P-Cr-Ni weathering steels with different nickel contents was studied in this research. It was found that NiO formed in the rust layer can promote the crystallization of corrosion products and improve the stability of the rust layer in the initial stage of corrosion. After a 72-hour corrosion test, Cu and Cr elements in the form of CuO and Cr2O3 further protected the matrix.

Summary: The corrosion behavior and mechanism of S500AW weathering steel in a sulfuric acid environment were studied. It was found that S500AW has a significantly lower corrosion rate compared to Q345B. The corrosion products of both steels contain Cu, CuO, and Sb2O3, which improve the adhesion of the corrosion product layer. The presence of Sb element reduces local acidity and enhances the corrosion resistance of S500AW in mild environments.

Summary: The rust layer of AlMn lightweight weathering steel in industrial atmosphere was studied in terms of structure, phase composition, elemental distribution, and electrochemical properties. The rust layer of lightweight weathering steel exhibits superiority in terms of these characteristics. The enrichment of FeAl2O4 in the inner rust layer refines the rust grain, increases the compactness of the rust layer, and produces an electronegative inner rust layer to block the S element. Mn content affects the corrosion resistance of lightweight weathering steel through MnO/MnO2, which alters the content of FeAl2O4 and α-FeOOH.

Summary: Rocks often cycle between dry and wet states due to precipitation and groundwater level changes, which can cause weathering especially in the presence of salt. This study focused on the effects of salt during wet-dry cycling on sandstone, a widely used building material. The research found that higher concentrations of NaCl led to more serious rock weathering, with salt crystallization increasing pore size and indirectly accelerating the weathering rate.

Summary: This study investigates the effect of different Cl- deposition conditions on the corrosion mechanism and electrochemical properties of rust layer for weathering steel. The research shows that low Cl- deposition leads to a three-stage corrosion rate while high Cl- deposition results in a two-stage corrosion rate. The increase of Cl- deposition affects the composition of rust layer and decreases corrosion resistance.

Summary: In-service monitoring of buried corrugated metal pipes and culverts is crucial to prevent sudden failure due to prolonged corrosion. This paper proposes an accelerated laboratory corrosion test to simulate the effects of chloride deposits on buried corrugated mild steel structures. The test shows that increasing the number of wet/dry cycles accelerates the corrosion and deterioration in steel strength, ductility, and hardness. The paper also presents a mathematical model for predicting corrosion damage based on physicochemical indicators.

Summary: This study investigates the atmospheric corrosion behavior of chromium-free complex-phase steel and explores its relationship with wet/dry frequency and ratio in cyclic corrosion tests (CCT). The results reveal that increasing the frequency and wet/dry stage ratio in CCT accelerates localized corrosion in the steel, but it may also intensify uniform corrosion.

Summary: This study investigated the impact of cementitious materials on the mechanical and physicochemical properties of sandstones through wet and dry cycling in different solutions. The concentration of precipitated Ca2+ was found to have the most significant influence on the sandstone properties. Mass loss and accumulation were observed in the sandstone after cycling in different solutions. Wave velocity variation analysis showed that the cumulative damage of sandstones subjected to cycling in cement solution was more severe compared to fresh sandstones. The deterioration process of sandstone by cement materials was found to be physicochemically synergistic.

Summary: Wet/dry cycling promotes the formation and transformation of FeOOH species in the rust layer, resulting in a lower content of Fe3O4/γ-Fe2O3 compared to continuous spray conditions. The rust layer formed under wet/dry cycling shows less compositional segregation and structural stratification. Wet/dry cycles facilitate the diffusion of oxygen and ions, leading to more uniform rust formation and evolution across the rust layer thickness.

Summary: X100 steel is highly susceptible to stress corrosion cracking (SCC), especially in the heat-affected zone (HAZ). The presence of chloride ions can lead to pitting and acidification, increasing local hydrogen levels and ultimately SCC susceptibility. The mechanisms involved in SCC of x100 steel include anodic dissolution (AD) and hydrogen evolution (HE).

Summary: The sulfur content has little influence on the tensile strength of C71500 alloy at high temperature, but significantly affects the elongation and reduction area of fracture. Sulfur inclusions, identified as (Mn,Fe,Ni)S, can deform plastically during hot deformation, leading to stress concentration and reducing the overall plasticity of the alloy. The processing maps with different sulfur contents demonstrate the destructive effect of sulfur on the high-temperature plastic deformation of C71500 alloy based on the proposed dynamic material model theory.

Summary: The anti-corrosion behavior of NiTi and CuNiTi arch wires were studied in artificial saliva. CuNiTi arch wire had more defects on the surface yet released less nickel compared to NiTi arch wire. Loading stress increased corrosion in both groups, but doping with Cu element reduced nickel release, possibly lowering the risk of metal allergy.

Summary: The microstructure evolution and properties of annealed cold rolling C71500 cupronickel alloy tube were studied using the electron backscatter electron diffraction (EBSD) technique. The texture of the cold rolling tube differed from that of drawing and sheet textures, with only RZ{111} and R-cube{001} textures observed after two roller cold rolling. Accumulated orientation differences were seen in the textures after a certain amount of deformation, creating favorable conditions for recrystallization nucleation. The alloy's tensile strength, yield strength, and micro-Vickers hardness increased with increased reduction of the tube wall.

Summary: This study analyzed the mechanical behavior of E690 high-strength steel sandwich panel affected by pitting corrosion. The depth of pitting corrosion and degree of pitting (DOP) damage were used to evaluate the mechanical behaviors of the panel. The results showed that pitting corrosion in the core of the panel greatly reduced the quasi-static compression and low-speed impact mechanical properties, while the pitting corrosion of the outer panel had no significant effect. Mechanical properties decreased with the increase of pitting corrosion depth and DOP, with DOP having a greater influence. The DOP of the outer panel had less effect on the mechanical properties of three-point bending compared to the core. Therefore, it is important to strictly control the pitting corrosion in the core of the panel to prevent adverse effects on its mechanical properties.

Summary: This study investigates the corrosion behavior of three NiTi shape memory alloys fabricated by laser-powder bed fusion (L-PBF) in a 0.9 wt.% NaCl solution at 37 degrees C. The passive film characteristics and corrosion resistance of L-PBF NiTi vary with their preparation process settings. The presence of defects, such as keyhole pores and cracks, on the L-PBF NiTi surfaces accelerates the passivation reaction process, but results in lower corrosion resistance compared to defect-free surfaces.
