Summary: The oxidation behavior and kinetics of partially crystalline Si2BC3N were studied at high temperatures, revealing weight loss due to gas release and the formation of loose oxide scales. Compared to completely amorphous Si2BC3N, partially crystalline Si2BC3N exhibited inferior oxidation resistance, possibly due to changes in superficial chemical compositions and reactivity during crystallization.

Summary: The study showed that Ti1-x-yAlxTayN coatings have improved protective properties at 850 degrees Celsius, but this effect diminishes at 950 degrees Celsius. Additionally, it was found that the protective properties of the Ti1-x-yAlxTayN coatings deteriorate with increasing Ta content, with only the Ti0.41Al0.49Ta0.10N composition providing effective protection for the titanium substrate.

Summary: The oxidation behavior of GTD-111 Ni-based superalloys with ultrafine-grained surface and polycrystalline counterpart in Ar + 20% O2 at 900 degrees C is studied. The presence of high diffusivity paths on the surface of the ultrafine-grained sample significantly increases the diffusion of scale-former elements and oxygen anions, resulting in a three-layer oxide film that ensures better oxidation performance. Grain refinement reduces the critical concentration of Al for forming a continuous alumina layer.

Summary: Accident tolerant cladding materials with improved properties under LOCA conditions are needed. FeCrAl alloys, with high-temperature steam oxidation resistance, show promise. However, the compositional effects on FeCrAl performance at operating conditions have not been well understood. This study investigates the effect of Al concentration in three Fe-17Cr-xAl alloys on oxidation resistance at 400°C in a steam environment, and finds that increased Al concentration can reduce total oxide thickness, enhance the formation of a uniform Cr-oxide layer, and allow for the formation of a Croxide, Al-oxide bilayer when Al concentration is sufficient.

Summary: The effects of C and N on hydrogen embrittlement (HE) were investigated. C and N increased tensile strength through solid solution hardening and high-density dislocation accumulation, with C being more effective than N in further strengthening through active TWIP effect. The lattice expansion caused by C and N reduced hydrogen diffusivity and depth of the hydrogen-affected zone, enhancing the resistance to HE. C further enhanced the resistance to HE compared to N due to lower hydrogen diffusivity, lower crack severity, and active cross slip.

Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated.

Summary: The oxidation behavior of Cf/ZrB2-SiC materials with different fiber architectures was investigated, showing that the good dispersion of ZrB2 particles in the polymer-derived SiC(O) matrix promoted the formation of compact oxide scales. It was found that a ZrB2 content of 20-30% in the material was a good compromise between lightness and oxidation resistance.

Summary: Unidirectional SiCf/SiC-matrix composites with a pyrocarbon interface were prepared by hot-pressing SiC nano powder at high temperature (1900 degrees C) and pressure (20 MPa). The volume fraction of SiC reinforcing fiber significantly affected densification and mechanical properties, with improvements in mechanical properties observed with an increase in fiber volume fraction up to a certain level, beyond which the ultimate strength degraded due to open porosity and fiber damage.

Summary: Various oxides and SiC have been proposed as candidate materials for electrical insulation coatings and inserts to suppress the MHD pressure drop in liquid metal fusion blanket systems. The radiation-induced conductivities (RICs), increases in conductivities by radiation excitation, have been evaluated on bulk and coated specimens. The results indicate that the RIC phenomenon would not prevent the MHD insulators from achieving the required performances.

Summary: This study systematically investigates the irradiation responses of binary W alloys, focusing on the binding energy of an alloying element with a W self-interstitial atom (W-SIA). Plates of W, W-0.3 at.% Cr, W-5 at.% Re, W-2.5 at.% Mo, and W-5 at.% Ta alloys were irradiated, and the formation of vacancy-type defects, the precipitation of alloying elements, and the changes in hardness were studied. It was found that the addition of Cr and Re effectively suppresses the formation of vacancy-type defects, while Ta and Mo have no significant suppression effect. Irradiation hardening was observed in all materials, but its degree was smaller in the W-5 at.% Re alloy.

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.

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.
