Summary: The high-temperature oxidation behavior of Fe-14Cr-9Mn-2.5Ni austenitic stainless steel in N2-21 vol%O2 environment at 900-1100 degrees C was investigated. With increasing oxidation temperature, the scale expands from a thin bilayer to a thicker multilayer composed of an outer Fe-rich layer and an internal oxidation zone. The inner oxide consists of island Cr-rich spinel precipitates surrounded by remaining Ni-rich metallic. At 1000 degrees C, an embedded Cr-rich dense layer was observed to slow down the oxidation rate. At a higher temperature (1100 degrees C), the outer oxide scale (Fe, Mn)2O3/(Fe, Mn)3O4/(Fe, Mn)O forms, and the oxidation rate significantly increases.

Summary: The oxidation kinetics and scale formation of 21-2N Stainless Steel alloys were investigated in a CO2 environment at 700℃. The study revealed the significant role of high manganese content in the formation of homogeneous oxide scale and as an FCC stabilizer in the alloy. Depletion of Mn resulted in an FCC to BCC phase transformation. Additionally, it was found that the oxide layer effectively prevented carbon uptake.

Summary: Understanding the growth mechanism of oxide layer on 316 L requires knowledge of reaction front position, oxide phase formation, and elements diffusion paths. By using Mn as a tracer in a new experimental approach, essential information of the early stages of oxidation up to 600 °C is obtained. The study suggests a previously undocumented role of Cr valence state during oxide growth, as Cr6+ is detected at 600 °C.

Summary: A new acidizing corrosion inhibitor composed of Mannich base and antimony salt was designed to effectively inhibit selective corrosion of duplex stainless steel in high-temperature and high-concentration acid systems. The developed corrosion inhibitors formed a double-layer membrane structure to block the diffusion of acid solution at high temperatures. The corrosion rate of 2205 duplex stainless steel in a simulated service condition showed excellent corrosion inhibition effect and no selective corrosion was detected.

Summary: The performance of LATP electrolyte with LiF and SiO2 additives was studied, and it was found that the additives can reduce the sintering temperature. Rietveld analysis revealed a mixture of NaSICON modifications with rhombohedral and orthorhombic structures. LiF acts as both a sintering additive and a mineralizer, but the orthorhombic structure negatively affects ionic conductivity.

Summary: The study shows that higher calcination temperatures lead to improved crystallinity of LATP samples, with distinct jump dynamics observed for different lithium ion species at various temperatures. Fast and slow lithium ions exhibit jumps in the nanoseconds regime near 300 and 700 K, respectively. The diffusion of lithium ions in LATP crystallites is limited by long-range ion migration, with a high self-diffusion coefficient observed at room temperature.

Summary: Solid-state sodium batteries (SSNBs) have gained significant attention for their high safety, abundant material resources, and low cost. One of the main challenges in the development of SSNBs is the suppression of sodium dendrites. This study explores the use of solid electrolyte Na3.4Zr2Si2.4P0.6O12 (NZSP) to inhibit dendrite formation, and the results show that surface-dendrite formation can be prevented by coating the surface with a sodium-salt coating. These findings have important implications for the further development of solid-state sodium batteries.

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.
