Summary: This study presents a new method of reinforcing metals using a three-dimensional metallic glass lattice. The results show that composites reinforced with metallic glass possess excellent mechanical properties, with higher plasticity compared to other types of composites. The enhanced performances are attributed to the well-designed structure and the interaction between metallic glass and stainless steel.

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: 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: A new laboratory-scale twin-roll caster was designed and manufactured to produce long and straight metallic glass composite (MGC) strips. Different Ti-based MGC strips were produced with varying in situ beta-Ti volume fractions at different temperatures. The mechanical behavior of MGC strips was found to be greatly influenced by residual stress induced by the thermo-mechanical effect during the twin-roll casting process.

Summary: In this study, a simple method was used to quantify the castability and glass-forming ability (GFA) of two SIM card slots with different designs, as well as at different casting temperatures. It was found that the Zr55Cu30Ni5Al10 (Zr55) alloy has a wider optimal casting temperature range compared to the Zr52.5Cu25Ni9.5Al7Ti6 (Zr52.5) alloy, indicating better GFA of Zr55. However, within the optimal casting temperature range, the castability of Zr52.5 was significantly better than that of Zr55 due to its lower melting point, poorer wettability to the copper mold, and higher optimal casting temperature. These findings provide guidance for the production of Zr-based bulk metallic glass components.

Summary: Rare-earth neodymium (Nd) addition has a significant influence on the glass forming ability (GFA) and mechanical properties of (Cu43Zr48Al9) BMGs, with the best performance observed at 3% Nd content and a compressive strength of 2045 MPa. The enhancement of GFA in Cu-Zr-Al BMGs with Nd addition can be well explained by the physical properties such as atomic size difference, electronegativity difference, and negative mixing enthalpy.

Summary: This study investigates the effects of three rejuvenation modes, namely biaxial loading, thermal pressure loading, and cryogenic thermal cycling, on Cu64Zr36 metallic glasses. The results show that biaxial tension loading leads to a rejuvenated glassy state with high strength, while thermal pressure loading achieves the greatest degree of rejuvenation at the expense of strength. Cryogenic thermal cycling results in a rejuvenated state with a lower strength drop compared to thermal pressure loading. These findings provide insights into the effect of rejuvenation modes on the microstructures and mechanical properties of metallic glasses, and offer guidelines for designing high-strength and superior plasticity metallic glasses for industry.

Summary: This study investigated the influence of parent austenite grain refinement on the intervariant boundary network in a lath martensitic steel. It found that refining the parent austenite grain led to a decrease in the fraction of certain boundaries in the martensite and an increase in the connectivity of low energy boundaries, ultimately improving the impact toughness.

Summary: Metastable beta Ti alloys based on the Ti-Nb system have attracted attention due to their unique properties. However, the unstable cyclic behavior of these alloys has hindered their widespread industrial use. Recent studies have shown that internal stresses, including those from dislocations, may be responsible for this behavior. This study demonstrates that inter-cycle thermal treatments can mitigate the unstable cyclic behavior, providing a significant breakthrough in our understanding of Ti-Nb superelastic materials.

Summary: This paper systematically investigated the evolution of microstructure in Fe-Ni-Co-Al polycrystalline alloys and its effects on mechanical properties. The results revealed that the migration of grain boundaries in different processes is driven by different factors, which impacts the grain orientation and precipitate formation. In the process of directional recrystallization, grains with specific orientations grow in the grain boundary region and form the dominant orientation, while grains with lower migration rate form the minor orientation. The alloy produced through directional recrystallization exhibited good recoverable strain and superelastic strain, while the alloy produced through solid solution treatment showed no evident superelastic behavior.

Summary: This study employed laser metal deposition to additively manufacture Ti-15Mo wt% alloy, and subsequently subjected it to post-fabrication uniaxial thermomechanical processing. The results showed that different zones in the microstructure remained after processing, and deformation mechanisms mainly involved slip and martensite formation. The compressive mechanical properties were found to be dependent on strain rate, with higher flow stress and compressive strength observed at higher strain rates. Grain structure homogenisation was not achieved, leading to anisotropic tensile properties.

Summary: This research aims to investigate the effect of roughing and finishing reductions on crystallographic texture. The results show significant heterogeneity in the centerline region, with higher intensity of certain textures. Drop Weight Tear Test indicates that steel specimens with lower and medium reductions exhibit superior low-temperature impact toughness compared to steel with higher reductions. The electrochemical hydrogen charging experiments confirm the presence of internal hydrogen cracks only in steel with lower and medium reductions.

Summary: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: This study explores the weldability, microstructures, and mechanical properties of two L1(2)-nanoparticle-strengthened medium-entropy alloys after electron beam welding (EBW). The results show that strong yet ductile defect-free joints were produced, with larger grain sizes in the fusion zones compared to the heat-affected zones and base materials. Both EBWed MEAs exhibited high yield strengths, high ultimate tensile strengths, and good fracture strains at 77 K. The V-doping improved the cryogenic mechanical properties of the TMT MEA.

Summary: The mechanical properties and microstructural evolution of C-doped TRIP-assisted HEA under dynamic loading conditions were systematically investigated in this study. The results showed that dynamic tensile deformation led to an increase in yield strength and a decrease in ultimate tensile strength, with a trend towards increased total elongation. The primary deformation mechanisms shifted from TRIP and TWIP effects to deformation twinning and dislocations. The presence of carbides formed through C-doping hindered dislocation slip and promoted the activation of multiple twinning systems.
