Summary: The study aimed to clarify the structural origin of the enhancement in glass-forming ability of binary NiNb metallic glasses. Ni62.5Nb37.5 alloy exhibited the best glass-forming ability and the densest atomic-packing structure among the four components, with a larger fraction of full icosahedral clusters. The glass structure in Ni62.5Nb37.5 MG was a heterogeneous mixture of interpenetrating icosahedral clusters, forming a chain-like network structure in the matrix. These Ni-centered icosahedra polyhedra played an essential role in controlling GFA.

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: 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: 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: Metallic glasses, especially Hafnium based MGs, have superior properties to conventional crystalline metals/alloys, with HBMGs having the additional advantage of high density. However, their glass-forming ability is limited. Our discovery of two HBMGs with a critical casting diameter significantly higher than the current record allows for the production of bigger products and easier manufacturing/processing.

Summary: The effect of substituting Zr with Sc on the glass forming ability (GFA) and mechanical properties of ZrCuNiAlTi bulk metallic glass (BMG) is reported in this study. It was found that the substitution of Zr with Sc improved the GFA of ZrCuNiAlTi BMG. The large atomic radius of Sc and small Gibbs free energy difference between the supercooled liquid and crystalline solid inhibited crystallization and improved GFA. Compression test results showed that the ZrCuNiAlTiSc BMG had increased plasticity and retained high fracture stress. The high relaxed excess free volume (REFV) in ZrCuNiAlTiSc BMG contributed to the increased plasticity.

Summary: The study reveals that the atomic dynamics of Zr in metallic glass-forming liquid is unexpectedly more active than Cu under super-high pressures, challenging the conventional understanding of the speed relationship between Cu and Zr atoms. It is also found that Zr can form shorter-bonded atomic structures under super-high pressures, leading to its exceptional atomic dynamics.

Summary: This study thoroughly investigated the glass-forming ability of Cu-Ag alloys at different compositions using molecular dynamics simulations. The results showed that the eutectic alloy exhibited the best glass-forming ability, with a critical cooling rate significantly lower than that of pure metals. The number of densely packed icosahedral-like clusters increased with increasing solute content in the alloy. While the dynamical properties of Cu-Ag melts were composition-independent at high temperatures, they clearly changed with composition at low temperatures.

Summary: The design and fabrication of metallic materials with high strength, high ductility, and high thermal stability is a long-sought goal in materials science. In this study, a new strategy was proposed to design and fabricate bulk amorphous-crystalline dual-phase alloys with superior properties. The nano-amorphous phase exhibited unexpected thermal stability and improved mechanical properties, increasing the fracture strength and strain of the alloy. Additionally, the alloy showed higher strength than commonly used high-strength aluminum alloys at elevated temperatures. This research provides a new approach and concept for designing high-performance alloys with a balance between strength and plasticity.

Summary: This study presents a facile and controllable manufacturing technology for hierarchical functional surfaces. Porous metallic glass was successfully manufactured using a water-dissolution material as a template and the excellent thermoplastic property of metallic glass. The prepared micro/nanostructures have excellent tunability, and the proposed approach can be used to prepare large-area disordered porous structures and ordered regular arrays with nanoscale replication accuracy. The disordered porous structure exhibited suitable properties for oil/water separation and maintained stable wettability even after exposure to strong acid or alkali environments and severe wear. The proposed strategy also showed excellent recycling properties.

Summary: The study proposes a novel method of using metallic glass as glue to bond different materials together, allowing for manual regulation of the mechanical, magnetic, and electrical performances of the composites by adjusting the ratios of metallic glass glue and admixture. Additionally, porous structures can be obtained and adjusted through dissolving a soluble admixture in water. This approach not only provides a new pathway for synthesizing composite materials with tailorable properties, but also opens up possibilities for multi-functional metal-containing composites.
