Summary: This article presents a new Co2FeSi glass-coated microwire with a nanocrystalline structure obtained using the Taylor-Ulitovsky technique. The annealing process significantly increased the size of the nanograins and resulted in the observation of perfect square hysteresis loops. The annealed samples exhibited dramatic magnetic behavior at low temperatures and showed critical temperature points where the magnetic behavior changed. The anomalous magnetic behavior can be attributed to the coexistence of ordered and disordered phases induced by annealing conditions. The presence of the glass coating influenced the magnetization behavior and mechanical properties of the Co2FeSi microwires.

Summary: The study investigates the aging process of supercooled Cu50Zr50 glass-forming liquid, revealing a multi-mode dynamics accompanied by a quantized hierarchy of mobile clusters. An aging model is proposed to describe the aging dynamics as a weighted average over quantized dynamic modes. This model predicts the heterogeneous dynamics in aging and equilibration of supercooled metallic liquids, shedding light on the intrinsic aspects influencing the aging process.

Summary: The development of Co-Ta-B-Si bulk metallic glasses with high glass-transition temperature, large compressive plasticity, high strength, and high glass-forming ability was achieved by accurately tuning the metalloid element contents of Si and B in the parental alloy. The improvement in plastic deformation was attributed to the self-organization behaviors of high-density shear bands.

Summary: In this paper, a machine learning-based predictive model was established to predict the glass-forming ability (GFA) of metallic glasses (MGs) using experimental data. The model achieved high accuracy in predicting the glass state formation and the temperatures related to MGs. Additionally, feature selection and visualization analysis methods were used to improve the interpretability of the model. Finally, a genetic algorithm was applied to optimize alloy composition for high GFA.

Summary: Liquid-to-liquid transition (LLT) in metallic liquids and its relationship with liquid dynamics were studied through in-situ vitrification, annealing, and heating processes. Isothermal-annealing induced forward and heating initiated reversible LLTs were detected, and the LLT mechanisms were revealed by controlling the annealing temperature. A two-step-like increase in specific heat reflected the coexistence of two distinct liquids. This study not only enhances our understanding of LLTs in metallic and molecular liquids, but also uncovers a unique first-order glass-to-glass transition in multi-component metallic systems.

Summary: Researchers have used geometric alignment and density-based clustering algorithms to quantitatively describe the short-range atomic structure in the liquid state of five metallic glass-forming systems. They found that each liquid is composed of geometrically-similar atomic clusters, and the distribution of these clusters is inversely correlated to the glass-forming ability observed experimentally.

Summary: CuZr-based bulk metallic glass matrix composites have unique mechanical properties compared to bulk glassy samples. The cooling rate during solidification determines whether a bulk metallic glass or a bulk metallic glass matrix composite can be formed. For the Cu45Zr48Al7 alloy, a minimum cooling rate lower than 40 K/s is required to allow partial crystallization of the B2 phase and observe the strain hardening effect.

Summary: By establishing quantitative correlations among compositions, elastic constants, GFA, and mechanical properties of metallic glasses (MGs), it is possible to predict their performance in advance. Experimental data confirms the validity of this predictive approach. A strategy for designing MGs with optimal combinations of strength, toughness, and GFA is proposed to allow for high-throughput discovery of glass formers with excellent mechanical properties.

Summary: This article explores the rapid cooling, or quenching, during the regeneration of seed gratings in standard single-mode silica optical fiber. The results show that the regeneration process can be divided into different stages in time. The novel method of split annealing offers a unique tool for optimizing regeneration and studying fundamental glass science within a one-dimensional bi-material system. We demonstrate regeneration at temperatures as high as 1200 degrees C for the first time, as well as opening up an approach suited to batch processing of regenerated gratings.

Summary: This study investigates an affordable method for obtaining micro/nanostructured surfaces using electrospray deposition (ESD) technique. By using this method, methylcellulose (MC) can form nanowire coatings, but is easily destroyed by water exposure. In order to enhance stability, the researchers explore the use of atomic layer deposition (ALD) to coat the MC nanostructures with Al2O3, resulting in superhydrophobicity upon subsequent heating. It is found that the size of the MC nanowires affects the trade-off between mechanical stability and hydrophobicity of the coated structures.

Summary: Electrospray deposition is a versatile coating technology that creates uniform micro-/nanodroplets through the competition between droplet surface charge and surface tension. Self-limiting ESD has been observed in certain conditions, leading to controlled film growth. By blending mechanical modifiers, the mechanical properties of the films can be tuned within the compositional ranges.

Summary: The authors propose a new method to measure the fragility of metallic glass forming liquids and find significant variations in fragility across Mg-Cu-Y alloys. Contrary to conventional understanding, low fragility does not necessarily correlate with high glass-forming ability. The introduction of crystallization complexity provides an additional contribution to modeling glass forming ability.
