Summary: This study systematically investigated the corrosion resistance and behavior of Ti-xMo titanium alloys in a 10% HCl solution. The results showed that increasing the Mo content enhanced the alloys' corrosion resistance and changed the corrosion type from uniform corrosion to pitting corrosion. Furthermore, increasing the Mo content and the quantity of beta-phase significantly improved the alloys' corrosion resistance.

Summary: Thermal treatment induces changes in phase composition and microstructural parameters of the alloy, which in turn affect its corrosion behavior in different solutions. In addition to phase composition, crystal orientation and the state of the alloy surface also play a significant role in overall corrosion behavior.

Summary: The effect of thermal ageing at 150 oC on the corrosion behaviour of Scalmalloy (R) alloy additively manufactured by laser powder bed fusion is investigated. The results show that cyclic polarisation curves, electrochemical impedance measurements, and mechanical tests exhibit similar results before and after the thermal treatment. However, electron microscopy characterisation reveals that the application of this temperature for sufficient time causes sensitization of the alloy to intergranular corrosion processes.

Summary: The corrosion behavior and mechanical property of 5083 Al-Mg alloy manufactured by additive friction stir deposition (AFSD) were compared with 5083-H112 alloy. AFSD can reduce the pitting corrosion susceptibility of 5083 alloy due to the refinement and re-dissolution of Mn rich secondary phase particles. However, the AFSD alloy has a more significant susceptibility to intergranular corrosion (IGC) due to the exfoliation of fine equiaxed grains after sensitization. This is attributed to the presence of beta-phase on the grain boundaries of the AFSD alloy, which is prone to acid attack.

Summary: The corrosion behavior of a Ti-6Al-3Nb-2Zr-1Mo alloy in hydrochloric acid was systematically investigated, revealing that increasing HCl concentration or temperature accelerates corrosion by promoting the breakdown of the protective oxide film and facilitating active dissolution of the alloy matrix. The rate-determining step in the corrosion process of the alloy is surface-chemical reaction rather than diffusion.

Summary: Annealing at higher temperatures increases the corrosion resistance of Ti80 alloy by forming a higher volume fraction of beta phase, which is more resistant to corrosion than alpha phase due to higher content of Nb, Mo, and Zr. However, severe corrosion is observed in 5 M HCl solution due to the breakdown of oxide films and micro-galvanic couple effects. These findings provide insights for designing Ti alloys with high corrosion resistance through microstructural optimization.

Summary: The parametric study identified specific conditions that lead to corrosion of mild steel in marginally sour environments, including temperature, H2S pH, solution pH, and sodium chloride concentration. Transmission electron microscopy revealed a porous layer containing mackinawite and magnetite, with corrosion initiating when the mackinawite layer broke down and exposing the steel surface to corrosive substances, leading to propagation of corrosion due to galvanic coupling.

Summary: The induced magnetic anisotropy, domain structure, and magnetic properties of nanocrystallized Fe72.9Si15.8B6.9Nb3.2Cu1Co0.2 material were investigated under continuous stress-annealing. The results show that the applied tensile stress during annealing can reduce coercivity and core loss by refining the alpha-Fe phase grain size. The annealed samples at higher temperatures exhibit negative correlations between remanence and permeability with induced anisotropy, which increases with the applied tensile stress. The stress-annealed samples demonstrate a magnetic easy plane perpendicular to the stress axis with a high induced anisotropy constant.

Summary: The effects of impurities H2O and O-2 in transported s-CO2 on the corrosion modes and kinetics of pipeline steels were investigated. Pressure is a key factor affecting the solubility of H2O in s-CO2 and corrosion extent, and a threshold pressure above which corrosion rate remarkably increases with pressure was identified. In-situ electrochemical noise (EN) technique revealed that corrosion in s-CO2 with H2O and O-2 is dominated by gas chemical reactions rather than electrochemical reactions.

Summary: Different geometries (wedges, rods, ribbons, and discs) of Ti40Zr10Cu32Pd14Ga4 and Ti40Zr10Cu32Pd14Sn4 bulk metallic glasses (BMGs) were prepared using suction casting, melt spinning, and splat quenching methods. X-ray diffraction measurements showed that the critical casting thickness of the Sn-containing BMG is at least 4 mm, higher than the Ga-containing BMG (2.1 mm) and the reference BMG (2.4 mm). Differential scanning calorimetry revealed a larger supercooled liquid region for glassy rods and ribbons compared to splat-quenched discs. The mechanical properties showed that the Ga-containing BMG has a higher plastic strain and a lower Young's modulus than the Sn-containing BMG and the reference BMG. Corrosion tests demonstrated that Ti40Zr10Cu32Pd14Sn4 has the highest pitting resistance among the BMGs tested. The Ga-containing BMG showed excellent biocompatibility.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: The oxidation behavior of FeCrNi medium entropy alloy was investigated through experimental observations and density functional theory (DFT) calculations. The study found that at 900 degrees C, the alloy forms a desirable and continuous oxide layer, while at 1000 degrees C, the oxide layer becomes discontinuous with penetration of oxide. These observations highlight the significant role of phase structure in promoting the formation of protective oxide scales and influencing oxidation resistance.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.

Summary: This work explores the correlation between electrolyte transport properties and the variation of pigment volume concentration (PVC) in organic coatings. An odd random phase electrochemical impedance spectroscopy (ORP-EIS) approach is used to analyze the diffusion of ions independent from water uptake. The results show that a higher PVC leads to a more homogeneous coating structure, resulting in faster diffusion of ions and enhanced water uptake.

Summary: The relationship between configurational entropy and lattice distortion in novel rare earth monosilicates was investigated, and the effect of configurational entropy on their properties was studied. The results showed that lattice distortion increased with the increase of configurational entropy, but a highly symmetrical crystal structure was formed when the configurational entropy was large enough, inhibiting the lattice distortion.
