Summary: Through the use of DSC, SEM, TEM, and XRD, we have discovered hierarchical transformations during the crystallization of Mg66Zn29Ca5 metallic glass ribbons. The activation energies for the crystallization process were calculated using different thermodynamic models. Our findings indicate the formation of short-range order patterns in Mg66Zn29Ca5 metallic glass and the impact of heating rate on crystallization and growth process. The phase transformations during annealing were also studied, revealing the formation and consumption of various metastable phases.

Summary: The combined effect of Mo and alloying order on the phase stability and mechanical properties of W-Re alloys was investigated using the first principles method. It was found that the short range ordered (SRO) W-Re structure is softer than that of random and ideal solid solution alloys, while the SRO W-Mo-Re structure possesses higher stability and strength than those of randomly distributed alloys. This study provides insights into the better design of alloy additions and control of alloy orders to modulate the softening and strengthening properties in W and W-Re alloys.

Summary: The formation and distribution of loose-packing and dense-packing regions in bulk metallic glasses (BMGs) can affect the macroscopic mechanical properties and the trade-off between strength and ductility. This study systematically investigates the structural heterogeneity caused by deep cryogenic treatment (DCT) and its effects on the deformation mechanisms in rejuvenated BMGs. The results suggest that the optimization of structural features, such as icosahedral short-range ordering (ISRO), can enhance the plasticity and strength of BMGs, leading to potential applications in designing BMGs with strength-ductility synergy.

Summary: We conducted a comprehensive study on the synthesis, structure, and magnetic properties of honeycomb oxide Na3Mn2SbO6 using neutron diffraction, heat capacity, and magnetization measurements. Our results confirmed a monoclinic structure and demonstrated the coexistence of long-range and short-range magnetic ordering. We also observed a spin-flop transition and identified the fully ordered magnetic ground state of Na3Mn2SbO6 as a Neel antiferromagnetic. These findings highlight the importance of developing new honeycomb oxides.

Summary: This study focuses on the relationship between the solubility of sulfur (as SO3) and the structure of Na2O-B2O3-SiO2 glasses. The research found an inverse correlation between the sulfur solubility and the degree of network polymerization in the glasses. While the modification of SO3 can compete with depolymerization mechanisms, the conversion of BO3 to BO4 induced by alkali cations is dominant. These findings have important implications for understanding the control of sulfur solubility in borosilicate-based nuclear waste glasses.

Summary: In crystals, lattice defects, such as dislocations, control mechanical deformation. Similarly, it is widely believed that even in glasses and liquids some kinds of defects, strongly disordered regions, play a major role in deformation. Recent results raise questions about the assumption that short-range order (SRO) in the nearest-neighbor cage of atoms determines defects in glasses and liquids.

Summary: The oxygen diffusion behaviors through barium-strontium aluminosilicates (BSAS), a typical EBC material, were studied. It was found that interstitial oxygen can stably exist and diffuse through BSAS, forming a complete three-dimensional diffusion network. The bond length of Si-Al-O was found to serve as a measure of interstitial oxygen diffusion in BSAS. The oxygen permeability of BSAS can be decreased by adjusting the proportions of alkaline earth elements present in the structure.

Summary: The study comprehensively investigates the effects of moire-induced lattice distortions on the superlubricity properties of twist MoS2/MoSe2 heterointerfaces through first-principles calculations. The results reveal that lattice distortions lead to localized electronic redistribution and orbital hybridization, resulting in band evolutions. Furthermore, a characteristic moire potential that periodically modulates the sliding energy barrier is observed, and its fluctuation is correlated with changes in interlayer charge density. This study provides essential insights into the nature of moire and superlubricity and paves the way for the development of advanced materials with excellent tribology performance.

Summary: Materials descriptors with multivariate, multiphase, and multiscale characteristics have been used to study the composition-processing-structure-property-performance (CPSPP) relationships in advanced materials. This study presents a hybrid data-driven and knowledge-enabled model to explain the composition-property-performance relationships, and applies it to design cost-effective superhard high-entropy diboride ceramics (HEBs). Machine learning and first-principles calculations are used to identify dominant features and validate the model. The results show that hardness is influenced by mean electronegativity, electron work function, and average d valence electrons of composition.

Summary: Si is a common alloying element in Al alloys, mainly used to form precipitates and improve castability. In this study, the effect of Si as a solute on work hardening and dislocation behaviors of Al-Si alloys was investigated. It was found that the addition of Si increased the tensile strength and ductility of the alloys, with higher Si concentrations resulting in greater improvements. The enhanced work hardening was attributed to the change in dislocation configuration and the weakening of stacking-fault energy.

Summary: Dislocation slipping and mechanical twinning control the plastic deformation of lamellar micro-structure (LM) in TiAl intermetallics. However, when the interlamellar spacing is reduced to the nanometer scale, the deformation mechanism switches to the development of long-period stacking-ordered (LPSO) structures. The formation of LPSO structures during deformation can result in greater high-temperature yield strength compared to LMs deformed via dislocation gliding or mechanical twinning.

Summary: The thermodynamics of ferroelectric materials and their ferroelectric to paraelectric (FE-PE) transitions are often described by phenomenological Landau theory and more recently by effective Hamiltonian and various potentials. In this study, the zentropy theory is proposed to predict the FE-PE transition without parameter fitting. By considering the total entropy of a system as a weighted sum of entropies of configurations and the statistical entropy among the configurations, the zentropy theory accurately predicts the FE-PE transition in PbTiO3 using first-principles domain wall energies as the only input parameter.

Summary: This study presents a first-principles-based approach to calculate finite temperature thermal and electronic transport properties. It can be used to model and understand structural evolution during electronic, magnetic, and structural phase transitions at the mesoscale. A computationally tractable model is introduced to estimate electron relaxation time and its temperature dependence. The model is applied to Ca3Ru2O7 to investigate the electrical resistivity across the electronic phase transition at 48 K. The quasiharmonic phonon approach and Boltzmann transport theory are employed to account for thermal expansion and calculate the temperature dependence of electrical conductivity.

Summary: This study investigates the correlations between galvanic corrosion, intermetallic compound formation, and welding energy input with regards to the initiation and propagation of micro-cracks in micropillars of resistant spot welding joints between aluminum and steel. The results show that higher welding energy leads to more severe corrosion and easier cracks initiation and propagation. Micropillars from the high welding energy region have a higher average yielding stress due to the thicker intermetallic compound layer.

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.

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.
