Summary: This study investigates the mechanical behaviors of ultra-fine grain (UFG) austenitic stainless steel compared to coarse grain (CG) counterpart. It is found that UFG exhibits higher nanohardness in both grain interior and grain boundary due to grain refinement effects. In the grain interior, the higher matrix strength of UFG is attributed to the lower density of pre-existing dislocations, requiring higher stress for nucleation and plastic deformation. On the grain boundary, the higher average P-c value indicates a higher shear stress required for dislocation activation, revealing a stronger grain boundary effect attributed to surrounding strains. The activation volume obtained from nanoindentation shows weak dependence on grain orientation but strong dependence on grain size.

Summary: Grain boundaries in stressed materials can cause stress discontinuities. Stress localization plays a crucial role in the behavior of materials, such as segregation, precipitation, and void nucleation. This study systematically investigates the stress state of a grain boundary perpendicular to a uniaxial external stress. The grain boundary with the most extreme stress discontinuity is determined for cubic materials within the elastic limit for a bicrystal model. The influence of elastic tensor components, C-11, C-12, and C-44, as well as grain orientation, is quantitatively studied.

Summary: This study investigates the mechanism of self-induced internal corrosion stress transgranular cracking, linking grain boundary wetting and diffusion to reveal the micro mechanism of crack formation in compositional gradient-structural intermetallic materials. Theoretical analysis shows that grain boundary wetting and diffusion induce dynamic internal stresses, leading to crack nucleation, while experimental results demonstrate the formation of stress concentration zones at grain boundaries where cracks preferentially nucleate and extend, resulting in transgranular fracture.

Summary: Kinetic and structural changes induced by Bi alloying in dilute Ni-Bi alloys were investigated, focusing on grain boundary phase transitions. The grain boundary diffusion of Ni in the Ni-Bi alloys was measured across single and two-phase regions of the bulk phase diagram. The results showed that the Ni grain boundary diffusion rates were dependent on the Bi concentration and were influenced by Bi segregation and multi-layer Bi segregation along the grain boundaries. The presence of a liquid layer of Bi at the grain boundaries resulted in the highest Ni diffusivity. Additionally, structural transitions between different grain boundary phases were found to have a significant impact on the grain boundary diffusion rates.

Summary: Copper joints have replaced solder interconnects in integrated circuits due to their great electrical properties and lower-temperature processing. To isolate Cu from oxidizing during bonding processes, a (111)-oriented nanotwinned Ag (NT-Ag) thin layer was electroless-deposited on a (111)-oriented NT-Cu film. The microstructures of the Ag films were then analyzed, showing that columnar NT-Ag grains epitaxially grew along the columnar NT-Cu grains. Additionally, the bonding strength of the Cu-Ag joints was found to be higher than that of the Ag-Ag joints, possibly due to the greater diffusion rate of Ag atoms in Cu than the self-diffusion of Ag.

Summary: This paper investigates the effect of grain size in the diffusion matrix on the grain boundary diffusion mechanism of Tb element. The results show that with only 0.75 wt. % TbF3 diffusion, the intrinsic coercivity increases significantly for the magnet with finer average grain size compared to the coarse-grain magnet. The increase in intrinsic coercivity is attributed to the increase in defect density and the higher grain orientation caused by grain refinement, which leads to improved diffusion efficiency and magnetic properties.

Summary: Traditional macro-scaled plasticity theories may not be fully valid in meso-/micro-scaled deformation studies due to size effects. The anisotropy of individual grains significantly affects the mechanical responses of polycrystalline metallic materials. Microcracks mainly initiate at grain boundary regions and grow along grain boundaries in meso-/microforming.

Summary: This study investigates temperature-induced disordering transitions of grain boundaries in body-centered cubic metals using classical atomistic simulations. The study reveals that gradual heating leads to continuous disordering of the grain boundary structure, accompanied by two complexion transitions, analogous to transitions described by the Berezinskii-Kosterlitz-Thouless-Halperin-Nelson-Young theory.

Summary: Atomistic computer simulations are used to investigate the atomic structure, thermal stability, and diffusion processes at the Al-Si interphase boundaries in composite materials. It is found that some stable orientation relationships observed in epitaxy experiments also exist at these interfaces. An interface-induced recrystallization mechanism can transform non-equilibrium interfaces into more stable states. Diffusion of Al and Si atoms in stable Al-Si interfaces is slower compared to diffusion in Al grain boundaries but can be accelerated in the presence of interface disconnections. A qualitative explanation for the sluggish interphase boundary diffusion is proposed, involving correlated atomic rearrangements in the form of strings and rings of collectively moving atoms.

Summary: To assess the oxidation behavior of bond coatings in thermal barrier coatings for gas turbines, vacuum plasma spraying (VPS) and high-velocity oxygen fuel (HVOF) processes were used. The VPS coating showed faster weight gain and the formation of a dense and thick thermal growth oxide (TGO) layer, while the HVOF coating demonstrated rapid weight loss and the suppression of diffusion due to alumina particles. The as-coated VPS coating had higher hardness and lower interfacial bonding strength than the HVOF coating. Diffusion induced by heat treatment led to similar internal hardness and bonding strengths in both coating layers. Improvement of the HVOF process requires densification of the coating layer and the formation of a uniform alumina layer on the surface to suppress internal oxide formation.

Summary: In this study, an improved discrete element (DE) model is proposed to simulate the delamination behaviors of thermal barrier coatings (TBCs) during micro-indentation tests, aiming to gain a better understanding of the failure mechanisms. The results show that the delamination of the coating interface involves two distinctive stages: crack initiation and propagation. Moreover, TBC systems with a thicker top are more prone to delamination due to reduced strain compliance.

Summary: This study reports the programmable manipulation of inorganic-organic interfacial electronic properties of ligand-functionalized plasmonic nanoparticles (NPs), which is crucial for their applications such as catalysis, photovoltaics, and biosensing. By functionalizing gold triangular nanoprisms (Au TNPs) with thiocinnamate ligands of varying surface dipole moments, the localized surface plasmon resonance (LSPR) properties of the Au TNPs in solid state can be reversibly tuned with a significant peak broadening. The shape of the NPs has a significant impact on the plasmonic response and work function modulation.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
