Summary: We conducted molecular dynamics simulations on metallic glasses to investigate the dynamics of shear band propagation. Our findings reveal that shear bands in metallic glasses exhibit supersonic propagation speed, microbranching, and velocity fluctuations, indicating intrinsic instability. The intersection of two shear bands under tension also leads to path deflection, speed slowing-down, and temperature rise at the junction region. These results suggest that shear bands in metallic glasses can be viewed as shear cracks in weakly nonlinear fracture mechanics theory.

Summary: The transformation-induced plasticity is a fundamental solution for improving the ductility of bulk metallic glass composites (BMGCs). The transformation redistributes the stress in the adjacent matrix, making interfacial regions potential preferential sites for shear band nucleation, which then enhance the ductility of BMGCs.

Summary: The study investigates the creep behavior of BMG at different loading rates, revealing that at low loading rates, serrated flow occurs while at high loading rates, homogeneous flow is observed. The rate-dependent creep behavior is attributed to the number of pre-existing major shear bands significantly influenced by the loading rate.

Summary: Based on microscopic mechanisms, a constitutive equation for crack-like propagation velocity and a flow model for bulk metallic glasses (BMGs) are derived. The model explains the fundamental deformation of BMGs and accurately predicts the transition between serrated and non-serrated flows.

Summary: This paper investigates the temperature rise in shear bands and its effect on crystallization behavior in bulk metallic glasses. The temperature profile inside and around shear bands is determined by the released elastic energy, shear band thickness, and energy transfer time. The size of the hot zone is found to be equal to the stable crack growth region, while the size of the liquid zone is equal to the vein pattern size on the fracture surface. Crystallization occurs around hot shear bands and inside cold shear bands, but only on the compressive side of the specimen. These findings provide valuable insights into the deformation behavior of bulk metallic glasses using an analytical approach.

Summary: The plastic yielding behavior of a brittle Fe-based metallic glass can be activated by decreasing the sample size to the micrometer scale. The yield strength of the brittle metallic glass was found to be at least 33% higher than the fracture strength measured with bulk samples. These findings clarify the physical nature of the strength of brittle metallic glasses and suggest the potential for using high-strength brittle metallic glasses in small-sized devices.

Summary: This paper investigates the time-varying formation tracking control problem for multi-agent systems (MASs). The main objective is to achieve asymptotic convergence of formation tracking error despite nonparametric and nonvanishing uncertainties. A fuzzy extended state observer (FESO) based on event-triggered mechanism is proposed to estimate unmodeled dynamics and external disturbances. Furthermore, a distributed control law is developed using neighborhood formation tracking errors, and total disturbance compensation is introduced to attenuate uncertainty influence in real time. The effectiveness of the proposed control protocol is demonstrated using a numerical example on unmanned aerial vehicle swarm system.

Summary: We report a novel low-cost FeNi0.9Cr0.5Al0.4 high entropy alloy with a unique fibrous heterogeneous solidification microstructure, which consists of fibers-like face-centered-cubic soft phases enveloped in nano-sized ordered body-centered-cubic hard shells. The fibrous microstructure is responsible for its notable mechanical properties, including a yield strength of -670 MPa, an ultimate tensile strength of -1196 MPa, and a uniform elongation of -21.1% at room temperature. The combination of high strength and good ductility is attributed to the hetero-deformation induced hardening mechanism generated from the soft-fiber and hard-shell interface. The cost-effectiveness and outstanding tensile properties make this as-cast FeNi0.9Cr0.5Al0.4 alloy an ideal candidate for structural applications.

Summary: This study investigated the effects of Konjac glucomannan (KGM) on the aggregation patterns and structural properties of weak, middle, and strong gluten. The results revealed that 10% KGM substitution resulted in decreased aggregation energy for middle and strong gluten, but increased for weak gluten. Additionally, 10% KGM enhanced the aggregation of glutenin macropolymer (GMP) in weak gluten, but suppressed it in middle and strong gluten. Furthermore, 10% KGM induced a transition from alpha-helix to beta-sheet in weak gluten, while causing more random-coil structures in middle and strong gluten. The network of weak gluten became more continuous with 10% KGM, whereas it was severely disrupted in middle and strong gluten.

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.
