Summary: This study investigates the mechanistic understanding of hydrogen embrittlement using in-situ transmission X-ray microscopy. It reveals both hydrogen-induced transgranular failure and intergranular failure with distinct fracture processes. The crack growth rate is higher for void-mediated intergranular failure than for slip-mediated transgranular failure.

Summary: The initial growth of a porous alumina layer and the hydrogen absorption during galvanostatic anodization were investigated. The nanostructure of the alumina layer varied with the anodization time, and a porous alumina layer was formed until the voltage reached its maximum value. Connected pores appeared in a steady-state voltage region, acting as hydrogen pathways. Delayed embrittlement was not observed in the substrate after anodization, attributed to the low amount of absorbed hydrogen. However, in the middle stage of anodization, a higher amount of hydrogen was trapped in the substrate/layer interface and resulted in delayed hydrogen embrittlement when subjected to stress.

Summary: The effect of Ni/Cu ratio on hydrogen embrittlement behavior was studied in a Cu-Ni binary alloy system. Two regimes were identified based on Ni fraction: Regime 1 with moderate hydrogen embrittlement when Ni fraction is less than 80 wt %, and Regime 2 with more severe hydrogen embrittlement when Ni fraction exceeds 80 wt %. Hydrogen-induced intergranular cracking was noted as the primary cause of hydrogen-induced degradation.

Summary: Factors promoting hydrogen-related intergranular fracture in tempered martensitic steel's elastic region were identified through frozen-in hydrogen distribution and tensile tests at -196°C. Results showed hydrogen embrittlement associated with intergranular fracture after precharging with hydrogen, while hydrogen embrittlement was also observed after preloading with elastic stress just before fracture strength at room temperature. The study revealed that reversibly accumulated hydrogen due to stress-induced diffusion onto prior austenite grain boundaries during stress loading at room temperature was responsible for intergranular fracture.

Summary: This article presents a nonlocal gradient-enhanced damage model that predicts transgranular and intergranular cracks in polycrystalline materials. The model considers the anisotropic linear elastic domains with random spatial orientation and cubic symmetries of the grains. Transgranular micro-cracks are described using a bulk damage variable, while intergranular fracture is incorporated through an interface damage variable and a cohesive law. The proposed computational framework utilizes an operator-split methodology for a robust and straightforward implementation.

Summary: Improvements in fracture performance of Al-Mg-Si extrusions are necessary for automotive market demands. The competition between trans-granular and intergranular fracture paths, influenced by slip bands and grain boundaries, affects the fracture mode and ductility. This study quantified the plastic strain distribution within grains for microstructures with different spacings of Mn dispersoids, indicating that reduced inter-particle spacing decreases local shear strain and stress concentration on grain boundaries, reducing the propensity for intergranular fracture. The presence of dispersoids shifts the fracture mode from intergranular to transgranular.

Summary: This study investigates the interactions between various interfaces and hydrogen in aluminum alloys using a comprehensive multiscale approach. The atomic scale relationship between different particle-matrix characteristics and susceptibility to hydrogen embrittlement (HE) is revealed. Depending on the nature of interfaces, they can either mitigate HE, provide hydrogen to sensitive sites, or act as crack initiation sites.

Summary: Obtaining intergranular and transgranular fractures through grain boundary engineering is an efficient technique to improve the effective fracture toughness of polycrystalline aggregates. The crack paths of different microstructures and the effect of grain aspect ratio on fracture toughness are analyzed. The results show that the effective fracture toughness can be increased by enlarging the aspect ratio of the grains but is still limited to the grain fracture toughness. This study provides valuable guidance for designing microstructures and improving fracture toughness in materials.

Summary: The objective of this study is to enhance the hydrogen embrittlement (HE) of commercial martensitic steel. Heat treatments are conducted, resulting in reduced mechanical properties but significantly improved HE resistance. Factors such as lesser dislocations, more MoyCx, and the presence of strained cementite interface positively contribute to the improved HE resistance. The presence of ferrite, which inhibits the propagation of hydrogen induced cracks (HICs), is another important factor leading to the lowest HE susceptibility.

Summary: The study revealed the occurrence of hydrogen embrittlement at both 177K and 298K, with hydrogen diffusion primarily along boundaries. At 77K, hydrogen was trapped due to active twin formation, preventing it from diffusing into stress-concentration regions, resulting in no significant hydrogen embrittlement.

Summary: In this article, a novel method for measuring the stress intensity threshold for hydrogen embrittlement (K-th) in industrial plating conditions was developed. The method involved plating side-grooved CT samples in industrial plating baths and measuring K-th using an incremental step loading methodology. The method was validated with a benchmark case and used on a test case to quantify hydrogen embrittlement. The study concluded that delaying the post-plating bake did not cause hydrogen embrittlement in the studied conditions. The presence of side grooves on CT samples increased the sensitivity to hydrogen embrittlement compared to smooth samples.

Summary: This study investigates the effect of anisotropy on the Hydrogen Embrittlement (HE) susceptibility of a 2205 Duplex Stainless Steel (DSS). The slip transfer across Grain Boundary (GB) is analyzed both experimentally and theoretically. Specimens sampled along the 45 degrees Rolling Direction (RD) exhibit remarkable HE resistance due to delayed microcrack initiation and slow evolution. Hydrogen-Assisted Cracks (HACs) often initiate at the austenite GBs due to the synergistic interactions between hydrogen-enhanced planar slip and slip transfer across GB, leading to stress/hydrogen accumulation and reduced GB cohesion.

Summary: This study investigates the impact of the microstructure of electrodeposited ZnNi coatings, particularly pores and microcracks, on the characteristics of hydrogen diffusion at room temperature. The results show that the presence of microcracks significantly affects the behavior of hydrogen diffusion, while the high grain boundary density in nanostructured coatings leads to a lower content of diffusible hydrogen.

Summary: In this paper, a combination of electrochemical measurements, surface analysis, and rheological measurements was used to study the impact of hydrolysed polyacrylamide (HPAM) on the corrosion behavior of carbon steel. The interaction between HPAM and inhibitor was also investigated for the first time. Adsorption isotherm analysis and XPS indicated that the corrosion inhibition properties of HPAM are attributed to the chemisorption of the polymer on the carbon steel surface. The introduction of inhibitor in the system resulted in increased viscosity and corrosion inhibition at 25 and 75 degrees C, due to the hydrogen bonding between HPAM and the inhibitor.

Summary: This study investigated the hydrogen embrittlement behavior of as-quenched and as-tempered martensitic steels under elastic straining in a high-pressure gaseous hydrogen environment for the first time. The difference in the total content of defects acting as H trap sites had the most significant contribution to the increase in absorbed hydrogen content under elastic loading. The as-quenched specimen experienced hydrogen-induced fracture during elastic straining in the hydrogen environment, while the tempered specimen remained unfractured under elastic loading.

Summary: This study investigates the resistance of progressively cold-drawn carbon steel wire against hydrogen embrittlement using analytical and numerical methods. The critical hydrogen content, critical hydrogen ratio, and embrittlement indices of different material conditions are determined. The wire with the highest degree of cold deformation exhibits the highest critical hydrogen content and improved resistance against hydrogen embrittlement, which is attributed to enhanced hydrogen trapping and changes in the lamellar spacing and orientation of the pearlite.

Summary: The susceptibility of metastable 304L to embrittlement in a high-pressure gaseous hydrogen environment was studied. The deterioration of mechanical properties caused by high pressure hydrogen gas can be accelerated by the presence of surface defects. Varying the machining parameters to change the density of defects caused by machining, it was found that the maximum dislocation density, rather than the maximum strain-induced martensite, increased the sensitivity to hydrogen embrittlement.

Summary: To understand hydrogen embrittlement mechanisms and prevent it in high-strength steels containing mixed-metal precipitates, researchers have employed a new experimental and simulation approach. They studied the local microstructure, hydrogen trapping, and crack path using various techniques such as SKPFM, high-resolution EBSD and HMPT, and TDS. These results were combined with a new method using high-energy synchrotron X-ray diffraction to observe the real-time distribution of hydrogen in the alloy. It was found that the mixed-metal precipitates in the alloy enhanced its resistance to hydrogen embrittlement due to irreversible hydrogen trapping by carbon vacancies inside the nanoprecipitates and the high total length of PAGBs. Additionally, direct evidence of carbon vacancies in the nanoprecipitates was observed for the first time using HAADF-STEM.

Summary: Aluminum alloys are commonly used in the liners of composite hydrogen storage tanks. The behavior of the liner when exposed to pressurized hydrogen and its permeability play a crucial role in determining its properties. This study employed a combination of hydrogen characterization techniques to investigate hydrogen permeability and the microstructure of an Al-Mg alloy. The competition between elastic and plastic deformations due to the pressure of gaseous hydrogen was found to determine the hydrogen permeability in the alloy.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
