Summary: The polarization behavior of Fe-34Mn-17Al-5Ni shape-memory alloy and pure Fe in NaCl-free and NaCl-contaminated Ca(OH)(2,sat) solutions were analyzed. It was found that FeMnAlNi exhibits more severe pitting corrosion sensitivity than Fe in NaCl-contaminated solutions. The pitting behavior is rationalized based on the different semiconducting properties of the passive oxides, analyzed by the Mott-Schottky technique.

Summary: The pitting corrosion behavior of AZ91 alloy before and after micro-oxidation treatment in 3.5% NaCl solution was investigated. The results showed that both the alloy and the MAO-coated alloy suffer from pitting corrosion and it is difficult for pits to stop growth. The air-formed MgO film, MAO coating, and corrosion products significantly influence the propagation behavior of pitting corrosion. The corrosion products on the MAO-coated alloy are very loose, leading to severe pitting corrosion.

Summary: The present study investigates the glass-forming ability, density change on crystallization, and corrosion behavior of newly developed rare-earth free Cu-based metallic glasses (CBMGs). The critical casting thickness of these new CBMGs increases with Hf content, as does the density. The corrosion resistance of the alloys also increases with Hf content and is influenced by the concentration of NaCl in the solution. The analysis of corroded samples confirms the formation of metal oxides and oxyhydroxides in the passive layer.

Summary: The research examined an additively manufactured aluminium alloy with high solute content, Al-14Zn-3Mg, which showed lower corrosion rate compared to a conventional wrought alloy, AA7075-T6. This difference was attributed to the microstructure and solute content of Al-14Zn-3Mg, specifically the absence of coarse intermetallic particles. Various tests were conducted to analyze the corrosion behavior of this new alloy manufactured through LPBF.

Summary: The influence of microorganism-induced surface modifications on the corrosion behaviour of 5083 H11 aluminium alloy was examined. Pre-immersion in natural seawater for 15 days to 2 months resulted in the formation of a dense oxy-hydroxyde layer on the AA5083 surface. This layer led to decreased cathodic and corrosion current densities, and increased passivity domain on the polarisation curves.

Summary: The study found that an increase in the density of high-angle grain boundaries can decrease the corrosion current of commercially pure Al alloy in chloride-sulphate solution, while intermetallic particles may act as pit initiation sites. In addition, the propagation of pits is strongly influenced by the density of high-angle grain boundaries.

Summary: Controlling precipitation through thermomechanical treatment is an important method to enhance the corrosion resistance of Al-Cu-Mg alloys. Cold rolling deformation can improve the resistance to intergranular corrosion in the solution-treated state, while cold rolling deformation in the retrogression-treated state changes the corrosion morphology from pitting to network corrosion.

Summary: The microstructure and corrosion behavior of Mg-8Li-3Al-2Zn(- 1.0Gd) alloys were studied. Galvanic corrosion occurs at the & alpha;-Mg/& beta;-Li phase interface in the homogenized LAZ832(-1.0Gd) alloys, while pitting corrosion occurs in the & alpha;-Mg matrix and & beta;-Li matrix. After hot extrusion, the corrosion form of the & alpha;-Mg matrix changes to intergranular corrosion. The corrosion resistance of LAZ832 alloy is effectively improved by combining Gd alloying and hot extrusion, with the as-extruded LAZ832-1.0Gd alloy showing the best corrosion resistance.

Summary: The study explores the crevice corrosion behavior of Alloy 690 in high-temperature chloride solution with different concentrations of thiosulfate and dissolved oxygen. Thiosulfate inhibits corrosion by consuming oxygen in aerated solution and promotes pitting corrosion by incorporating into oxide films in deaerated solution, influencing their composition and thickness. The mechanisms of thiosulfate and dissolved oxygen on crevice corrosion in high-temperature chloride solution are discussed.

Summary: This study proposes the use of Scanning Electrochemical Cell Microscopy (SECCM) to collect corrosion activity from random locations on 316 L SS. Pitting corrosion was triggered by potentiodynamic polarization tests in the presence of chloride. Data science methods were employed to analyze 955 j Vs E curves and understand the conditional log(j) distributions at different potentials. The study found that the log(j) distribution was potential-dependent and became more random with increasing testing aggressiveness.

Summary: This study investigated the mechanical properties, composition distribution, microstructure, and fracture behavior of an Al-Cu wheel made from a new Al alloy using liquid-die forging. The results showed significant Cu segregation in the wheel specimen, with a microstructure consisting of casting and deformed structures. The best heat treatment and water quenching system consisted of solution treatment at (530 ± 5) °C for 4 h, followed by (535 ± 5) °C for 24 h, and aging treatment at (155 ± 5) °C for 4 h. The fracture mechanism of the Al-Cu wheel was intergranular fracture.

Summary: In this study, a 4 wt.% TiB2/Al composite with non-dendritic microstructures was fabricated using ultrasonic-assisted squeeze casting. The effects of different casting temperatures on the microstructures and mechanical properties of the as-cast composites were investigated. A short process semisolid billet preparation route was developed, and the thixoformability of the as-cast composite was analyzed by thixoforging a complex-shaped part. The results showed that decreasing the casting temperature improved the microstructures and mechanical properties. The semisolid billets with fine and near-spherical solid grains were successfully prepared by partial remelting the casting billet at 628 degrees C for 5 minutes. A connecting rod with favorable forming quality was forged from the as-cast billet using the short process thixoforging. The thixoforged part exhibited improved yield strength, ultimate tensile strength, and elongation compared to the casting billet, thanks to the deformed solid grains, refinement of TiB2 particles, and eutectic phases.
