Summary: In the study, the development of microstructures in an Fe-22Mn-0.6C-1.5Al TWIP steel during thermomechanical processing was investigated. The effect of different processing conditions on the mechanical properties was examined, and it was found that the addition of aluminium eliminated stress-strain curve serrations, ensuring stable plastic flow. The accumulation of stacking faults during rolling facilitated the formation of twins, resulting in excellent mechanical properties and small grain size.

Summary: By high-pressure torsion processing, an austenitic stainless steel forms a hierarchical nanostructure with double the hardness value compared to the coarse-grained counterpart, which can be maintained at temperatures up to 600 degrees Celsius. Annealing treatment at temperatures from 400 to 600 degrees Celsius can induce recovery of the hierarchical nanostructure, reducing microstructural heterogeneity and increasing hardness.

Summary: This study investigates the effects of grain refinement on the tensile properties, dynamic strain aging (DSA), and twinning behavior of Fe-16Mn-0.6C steel. The results show that decreasing the grain size enhances the yield strength, tensile strength, and elongation of the steel. Grain refinement also increases the serration amplitude and local strain concentration of DSA, leading to a stronger DSA effect. Additionally, fine-grained steel exhibits delayed twinning behavior but continuously produces fine and dense twinning structures at high strains, contributing to the strain-hardening capacity and simultaneous increases in strength and ductility.

Summary: Microstructure analysis of a Fe-25Mn-2Al-0.1C steel under uniaxial tension showed a gradually decreasing three-stage strain hardening behavior. Deformation twinning and dislocations cells were observed near failure strain, with dislocations seeming to play a more dominant role in strain hardening than twinning.

Summary: This study evaluates the effect of ultrasonic impact peening (UIP) on the stress corrosion cracking (SCC) susceptibility of gas tungsten arc welded (GTAW) stainless steel (SS) components, aiming to control the SCC failure. The study found that UIP treatment induces residual compressive stresses (RCS) and severely plastically deformed (SPD) layers on the surface, resulting in improved SCC resistance. These findings suggest that UIP is a potential technique to mitigate the SCC susceptibility of austenitic-based stainless steel (ASS) weld joints in nuclear applications.

Summary: A finite-strain phase-field model is proposed to study the coupled deformation twinning and crystal plasticity. Twinning is treated as a volume-preserving stretch and a micromorphic formulation is employed. In the model, each pair of conjugate twinning systems is represented by a single twin deformation variant, and a single order parameter is used to consistently describe the two conjugate twinning systems.

Summary: We analyze the effects of the initial 3D printed microstructure of 316 L stainless steel on subsequent deformation behavior. Deformation twinning occurs at lower strains in 3D printed samples, and twins are thinner and intersecting inside some grains. Pre-existing dislocation structure in the 3D printed samples facilitates deformation twinning. The study provides fundamental ideas for microstructural engineering of 3D printed metals for better mechanical properties.

Summary: The study investigated the effect of cathodic polarisation on stress corrosion cracking behavior of peak-aged Ni(Fe, Al)-maraging steel in artificial seawater. It found that the steel exhibits better compatibility of strength and hydrogen embrittlement resistance due to the abundant and evenly dispersed Ni(Fe, Al) nanoprecipitates. The mechanism of SCC at different potentials and a novel model for interpreting hydrogen embrittlement were proposed.

Summary: The effect of elastic stress on the rust layer of S450EW weathering steel formed in salt-spray was studied, revealing that stratification of the rust layer is mitigated with increased stress level on the steel. The segregation of the magnetic Fe3O4/gamma-Fe2O3 phase in the inner sublayer was reduced by stress through a mechanism associated with the magnetomechanical effect, regressing the magnetisation of the steel matrix.

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: The local corrosion behavior of the coarse-grained heat-affected zone (CGHAZ) of a Zr-Ti-Al-RE deoxidized steel was investigated. It was found that the modified inclusions consisting of a (Zr-Mg-Al-Ca-RE)O-x core claded by a CaS and TiN shell. The dissolution of CaS first, followed by the oxide core, leaving TiN parts. This study indicates that the addition of rare earth can reduce lattice distortion and prevent galvanic coupling, while the chemical dissolution of CaS causes localized acidification and pitting corrosion initiation.

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.
