Summary: This research provides a practical guideline to significantly reduce production costs of metallic glasses (MGs) through tailored alloy design and precise control of thermoplastic forming (TPF) process parameters. It is discovered that commercially available MGs with a low glass transition temperature (Tg) can be developed in the Zr-rich alloy systems. Moreover, the challenge of maintaining a wide TPF window in Be-free Zr-based MGs while keeping Tg low has been addressed.

Summary: This study provides practical guidelines for tailoring the thermoplastic forming (TPF) process in bulk metallic glasses (BMGs) and investigates the influence of process variables. A continuous heating transformation (CHT) diagram was constructed for LM1b (Zr44Ti11Cu10Ni10Be25) using Flash-DSC measurement, and three TPF procedures from bulk to nano scales were demonstrated. A new TPF parameter, P, was proposed to compare the TPF ability of different BMGs. These results enable the selection of suitable BMGs and optimization of TPF processes, leading to improved performance and expanded applications in various industries.

Summary: This study summarizes recent advancements in the thermoplastic drawing of bulk metallic glasses. By combining drawing with templated embossing, arrays of high-aspect-ratio nanostructures can be fabricated, which was not possible with previous drawing methods limited to single fibers. Two-step drawing allows the production of challenging metallic glass structures such as vertically aligned nanowires, nanoscale tensile specimens, hollow microneedles, helical shafts, and micro-yarns, which are difficult to fabricate using other thermoplastic forming techniques. These geometries have the potential for new applications in sensors, optical absorption, transdermal drug delivery, and high-throughput characterization. The review focuses on the development of experimental setups, quantitative descriptions of the drawing process, and the versatility of the drawing methodology.

Summary: The microstructure, thermomechanical properties, and high temperature plastic deformation behavior of Zr55.7Cu22.4Al14.7Ni7.2 alloy rods were investigated. The alloy showed non-Newtonian fluid properties under low temperature-high strain rate conditions, while it exhibited the deformation behavior of a Newtonian fluid under high temperature-medium to high strain rate conditions. The alloy crystallized after deformation at high temperature and low strain rate, while maintaining an amorphous structure in the low and medium temperature region. High temperature deformation also affected the Vickers microhardness of the metallic glass.

Summary: Scanning/transmission electron microscopy (S/TEM) techniques have been used to analyze shear bands in metallic glasses for decades in order to improve their mechanical properties. However, conventional S/TEM lacks the ability to directly characterize the local strain and atomic structure of amorphous materials. In this study, 4-dimensional-STEM (4D-STEM) is applied to directly map and correlate the local strain and atomic structure at the nanometer scale in deformed metallic glasses. The results provide a new understanding of the formation of shear bands in metallic glasses.

Summary: Understanding the crystallization mechanisms in nano-sized metallic glasses (MGs) is crucial for the manufacturing and application of these new nanomaterials with unique structural and functional properties. Through molecular dynamics simulations and atomistic visualization, we address important questions regarding nucleation and growth modes in MG nanorods. Our study shows that nucleation predominantly occurs on the surface of nano-sized MGs, while the growth mode and resulting grain structure depend on the nanorod diameter. This atomistic insight provides valuable information for the development and utilization of nano-sized MGs.

Summary: In this study, the magnetic behavior and magnetocaloric effect of high-entropy and medium-entropy bulk metallic glasses (BMGs) were systematically investigated. The results showed spin glass-like behavior and large magnetocaloric effect at cryogenic temperatures in all BMGs. The influence of configuration entropy on magnetic response and magnetocaloric effect was discussed. It was found that configuration entropy could alter magnetic phase transition temperature, magnetic hysteresis, and refrigeration capacity in these BMGs. However, increasing configuration entropy did not lead to distinct differences in magnetic entropy change. The BMGs in this study exhibited good glass-forming ability and promising magnetocaloric effect, making them potential candidates for cryogenic refrigerants.

Summary: The metallic glass rods of RE55Co17.5Al27.5 (RE = Gd, Tb, and Dy) with critical diameters of 8 mm were successfully fabricated using the copper-mold suction casting method. By replacing Gd with Tb and Dy, the thermal stability was improved while the Curie temperature decreased, attributed to the strong f -d hybridization and weak magnetic exchange interaction between Co and Tb/Dy. Discussions were made on the reversed trend of glass transition temperatures Tg and Tc based on around 33 RE-based metallic glasses, revealing the competition between dominant thermal effect and magnetic exchange interaction. Dy55Co17.5Al27.5 exhibited relatively strong dynamic behavior and a wide supercooled liquid region of 66 K, showing high cooling efficiency in the hydrogen liquefaction temperature range due to its low Tc below 50 K and rapid response to applied magnetic field stemming from its large 4f electron number and low G-factor.

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.

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: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
