Summary: In hot compression of a near alpha high temperature titanium alloy, the rapid drop of peak flow stress is closely related to the dynamic transformation from alpha phase to beta phase induced by deformation at elevated temperature. Higher deformation temperature and lower strain rate contribute to accelerating the dynamic transformation and drop of peak flow stress.

Summary: This study attempts to investigate the synergetic effects of changes in alloying elements and the hot extrusion process on the microstructure, texture, and mechanical properties of Mg-ZnxZr-yCa alloys. The research reveals that the texture of the alloy becomes more equiaxed after hot extrusion, and the tensile strength decreases compared to Ca/Zr=1. Atom probe tomography technique confirms that solute elements segregate into grain boundaries, facilitating the phenomenon of texture weakening in extruded alloys.

Summary: The mechanical properties of the GWZ1152 alloy, including ultimate tensile strength, were systematically studied at both room and high temperatures. It exhibited excellent strength at room temperature and maintained relatively high strength as the temperature increased. The outstanding heat resistance can be attributed to various factors, such as fine grain structures, certain phases, and nano-scale precipitates in the alloy.

Summary: Utilizing friction stir processing, an ultrafine-grained structure was achieved in Mg-Zn-Y-Zr alloy leading to extraordinary superplasticity. Grain refinement and homogeneous dispersion of precipitates were promoted by the coupled thermo-mechanical effect, resulting in an ultra-fined grains size of 1.9 +/- 0.4 μm and a superplastic elongation of 642%. Grain boundary sliding was considered as the predominant superplastic deformation mechanism in ultrafine-grained materials.

Summary: The hot deformation behavior of dual-phase Mg-9Li-3Al alloys was investigated through isothermal hot compression tests. Flow curves exhibited periodic fluctuation at high strain rates, which can be considered as the Portevin-Le Chatelier effect. The relationship among flow stress, strain rate, and deformation temperature was analyzed, and the deformation activation energy and basic material factors were calculated. A processing map composed of power dissipation and instability domains was established to reveal the hot workability. The formation of needle-shaped a-Mg phase was attributed to the deformation-induced transformation.

Summary: This study investigated the microstructures, mechanical properties, tensile deformations, and strengthening mechanisms of Al-Mg alloys with different Mg contents. Higher Mg content resulted in higher fractions of C15 phases and increased yield strengths. The 9Mg alloy exhibited better resistance to serrated flow due to its fine equiaxed grains and higher Mg content and number densities of obstacles. Solid-solution and grain-boundary strengthening contributed to the overall yield strength. The study demonstrated the potential of conventional models to accurately predict the yield strengths of Al-Mg alloys.

Summary: The tensile behavior of extruded and peak-aged Mg-5Gd-3Y-xZn-0.5Zr alloys was investigated in terms of microstructural evolution, deformation modes, and mechanical properties at temperatures ranging from -100℃ to 300℃. The study found that the Zn content affected the distribution of intragranular and interdendritic phases, which in turn influenced the mechanical properties of the alloys. Additionally, the deformation modes during tensile testing were influenced by factors such as testing temperature, grain orientation, and LPSO morphology.

Summary: We investigated the air-sensitivity, atomic structure, and magnetic anisotropy of VI3 single crystals. Our results showed that VI3 nanocrystals have a large M-R/M-S ratio of about 0.75 and a uniaxial anisotropic constant of approximately 10(5) erg cc(-1) below the Curie temperature. Moreover, density functional theory calculations demonstrated that both monolayer and bulk VI3 exhibit ferromagnetic insulating properties, with the magnetic moment primarily originating from the d orbital of the V atom. These findings provide a feasible approach for fabricating TEM specimens of air-sensitive layered materials and enhance our understanding of the layered ferromagnetic VI3.

Summary: Fiber-like p-CuO/n-ZnO heterojunction gas sensing materials were prepared to detect the decomposition byproducts of SF6: H2S and SO2. The sensors showed excellent performance in detecting H2S and SO2 with higher and faster response-recovery time. The sulfuration-desulfuration reaction between H2S and the sensing materials might contribute to the enhanced sensor performances. Furthermore, the sensors exhibited high response to low exposure of H2S and SO2 gas.

Summary: By combining transmission electron microscopy, first-principles calculations, and cathodoluminescence spectroscopy, we demonstrate unexpected strong interfacial interactions at the incoherent AlN/Al2O3 (0001) interface with a large mismatch, which result in the formation of misfit dislocation networks and stacking faults rarely observed at other incoherent interfaces. The strong interfacial interactions significantly tailor the interfacial atomic structure and electronic properties, leading to a reduced band gap and strong interfacial ultraviolet light emission. These findings suggest the potential of incoherent interfaces in developing novel heterojunction materials and devices.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
