Summary: Thermoforming in the supercooled liquid region can achieve high strain-rate-sensitivity and superplastic ductility. Incipient deformation-induced crystallization and stress-assisted free volume change lead to a transition from Newtonian to non-Newtonian flow. Factors such as heating rate, processing time, and the extent of the supercooled liquid region significantly affect the structural stability. Increasing the deformation temperature enhances superplastic behavior, but high temperatures may promote crystallization and loss of superplastic ductility. Future research directions include optimizing the structure and preparation methods of metal glass-based composites and improving thermoplastic formability.

Summary: The mechanical properties of cellular metallic glasses are influenced by the shape of their cellular structures. Random structures with uniform porosity show higher yield strength and Young's modulus compared to microlattice structures. The chiral structure displays the highest Young's modulus, while stochastic cellular structures exhibit higher energy absorption capacity.

Summary: The relationship between microstructure and mechanical property of three Zr-based bulk metallic glasses (BMGs) was investigated. The results show that the content of CuZr2-type phase increases but that of Zr6Al2Ni-type phase decreases with increasing Zr content. The plastic flow stress and strain decrease while the plasticity increases with increasing fraction of CuZr2-type cluster, which is named as geometrically unfavorable motifs (GUMs). The fitting parameters from cumulative probability statistics provide valuable clues for investigating the plastic flow and plasticity of the BMGs.

Summary: Molecular dynamics simulations are used to investigate the mechanical properties of nanoporous CuxZr1-x metallic glasses. The study reveals a strong correlation between Young's modulus, Ultimate Tensile Strength (UTS), and porosity/composition. Increasing porosity leads to a change in nanoporous topology and a transition from brittle to ductile deformation and failure mechanisms. Genetic Programming (GP) is employed to establish scaling laws for E and UTS as a function of porosity and composition, accurately predicting their values in the entire range considered.

Summary: A family of novel Os-Co-Ta-B high-temperature bulk metallic glasses (HTBMGs) with high glass transition temperature, Vickers microhardness, and compressive strength was fabricated by introducing high-modulus refractory metal Os and strong-covalent metalloid B. The impressive strength is attributed to the strong bond characteristics especially for Ta-Os and B-B bonds. The castable OsCo-based HTBMGs with superior mechanical properties and high thermal stabilities are significant for high-temperature applications as advanced structural materials.

Summary: This paper explores the relationship between atomic structure and mechanical properties of metallic glasses by using molecular dynamics simulation. The study found that changes in mechanical properties can be linked to short- and medium-range ordering in the atomic structure. Structural statistics, such as Voronoi analysis, were used to determine the mechanical properties of the metallic glass.

Summary: This study shows that minor alloying can enhance the strength of metallic glasses by increasing the chemical bond strength, which is distinct from changes in topological ordering. The addition of transition metals to Al-Sm based metallic glasses increased their hardness, mainly due to the strong bonding between transition metals and aluminum atoms. The effects of topology and chemistry on the mechanical properties of metallic glasses are independent of each other, providing insights for the design of metallic glasses with improved mechanical properties.

Summary: This study investigates the depth-dependent mechanical properties of Zr-based bulk metallic glasses using the depth-sensitive nanoindentation technique. The results show that the surface hardness and elastic modulus increase, while fracture toughness decreases with decreasing indentation depth. This mechanical size effect is closely related to the evolution of shear bands at different depths.

Summary: By utilizing Fourier analysis, this study establishes an analysis protocol to quantitatively measure the spatial heterogeneity of metallic glasses, revealing a hierarchy of spatial heterogeneity inherited from thermal processes. The trends of spatial heterogeneity under mechanical loadings provide valuable information about shear instability onset, and a positive correlation between initial nanoscale heterogeneity and material ductility is found. This analysis protocol offers a new way to explore the structure-property relationship for disordered materials.

Summary: The effect of Ti substitution for Cu on the glass forming ability (GFA) and mechanical properties of Zr60Cu(20x)Al10Ni10Tix (x = 0, 1, 3 and 5at.%) bulk metallic glasses (BMGs) was investigated. The addition of Ti improved the GFA of Zr-based BMGs, as indicated by the increase in supercooled liquid region range from 47 K to 79 K. The plasticity and fracture strength of Zr-based BMGs significantly increased with Ti addition, reaching a peak value of 25.3% and 2315 MPa, respectively. The hardness and elastic modulus of Zr-based BMGs were also significantly improved with Ti addition.

Summary: Intervertebral fusion surgery is a major operation for spinal trauma, degeneration, and deformity correction. Most fusion cages have high stiffness, leading to stress concentration and shielding effects. Using a porous structure in fusion cages can reduce stiffness and improve strength for surrounding tissues. The study designed a porous gradient structure intervertebral cage and evaluated it through simulations and mechanical property testing.
