Summary: Laser additive manufacturing has the potential to fabricate metallic glasses with arbitrary geometries. However, the thermal stress induced by the manufacturing process can cause internal cracks in the materials, leading to reduced fracture toughness. To solve this problem, researchers successfully introduced the B2 phase into Zr-based metallic glass composites, which improved fracture strength by inhibiting crack generation and premature shearing-off.

Summary: This study investigates the microstructures and mechanical properties of 50 wt% Nb-reinforced Zr-based bulk metallic glass composites (BMGCs) manufactured via laser directed energy deposition (LDED) with two different laser powers, and compares them with those of LDED manufactured monolithic bulk metallic glass (BMG). The results show that both BMGCs have a multi-component microstructure, while the monolithic BMG contains only one component. The nanocrystals at the melt-pool boundaries embrittle the monolithic BMG, resulting in higher yield strength but negligible plastic deformation. In contrast, both BMGCs exhibit significant plastic deformation due to the reinforcement of Nb, which improves plasticity and reduces the volume fraction of nanocrystallites at the melt-pool boundaries. The BMGC manufactured at higher laser power exhibits higher shear band plasticity, despite having higher volume fraction of nanocrystallites and lower enthalpy of relaxation. The load transfer characteristics of the Nb-BMG matrix interfaces in the two BMGCs are analyzed and rationalized.

Summary: This study examines the variations in structure and properties of Zr-based bulk metallic glasses (BMGs) processed by laser powder bed fusion (LPBF) along the build height. The results reveal a softer amorphous structure at the bottom compared to the middle region, with the top region displaying intermediate characteristics.

Summary: The fully amorphous Zr52.5Cu17.9Ni14.6Al10Ti5 bulk metallic glass samples with a relative density exceeding 98% were fabricated via selective laser melting (SLM), achieving high fracture stresses and reproducible plastic strain. The observed serrations during compressive loading suggest distinct shear-band dynamics in the additively manufactured samples compared to as-cast glass. Despite the presence of uniformly dispersed spherical pores and pronounced heterogeneity, shear bands are straight and form in the plane of maximum shear stress, indicating the potential for manipulating deformation behavior through tailoring porosity and structural heterogeneity in additive manufacturing.

Summary: This study investigated the tribological properties and wear mechanisms of ex-situ additively manufactured FeCrMoCB/Cu bulk metallic glass composite under different normal loads and sliding speeds. The findings showed that the composite exhibited good wear resistance, with the coefficient of friction decreasing and the wear rate increasing as the sliding speed increased. Additionally, the wear mechanisms shifted from abrasive wear to oxidation wear and adhesive wear with increasing normal load, and adhesive wear and fatigue wear became dominant as the sliding speed increased.

Summary: A Ti-based BMG was successfully manufactured using an additive manufacturing process based on laser powder bed fusion technique. The crystallization behavior was found to be influenced by energy density during 3D printing processes using amorphous powders. Higher energy density led to more inner defects and increased crystallization in the BMG parts.

Summary: The fracture toughness of nanolaminated graphene/aluminum composites was investigated, which exhibited a tensile strength exceeding 300 MPa. The results showed fracture toughness values exceeding 20 MPa root m, with negligible anisotropy for two cracking orientations. This approach of bioinspired nanolaminated metal matrix composites overcomes the trade-off between strength and toughness in pure aluminum by promoting crack blunting, deflection, and bifurcation.

Summary: The study aimed to analyze how different process parameters control the size and properties of submicrometer chitosan particles loaded with DCPA. Solutions of 10 mg/mL chitosan and 2.5 mg/mL DCPA in a 90% acetic acid were electrosprayed under three distinct flow rate conditions: 0.2, 0.5, and 1.0 mL/h. The particles were characterized in terms of morphology, inorganic content, zeta potential, and minimum inhibitory concentration (MIC) against S. mutans. The results showed that a flow rate of 0.5 mL/h presented the best compromise solution in terms of morphology, zeta potential, MIC, and inorganic content.

Summary: This study experimentally investigates the fatigue crack growth rates of three different grades of ultra-high strength steels (S700, S960 and S1100) in welded components. The fatigue material constants for different regions of the welded components are determined, and comparisons are made with literature results. It is found that the S700 base material has the lowest fatigue crack propagation resistance, and laser welding outperforms gas metal arc welding in terms of fatigue crack growth resistance.

Summary: This study characterizes the impact of phase transformations on the room-temperature irradiation tolerance of a nanocrystalline TiZrNbHfTa RHEA. Results show that the alloy demonstrates exceptional irradiation tolerance after 500°C treatments for 1-100 h, with minimal irradiation-induced hardening. However, 800°C treatment for 1 h negatively impacts the mechanical performance, causing significant irradiation-induced hardening and embrittlement.

Summary: Metallic glasses can have various atomic arrangements determined by processing history, influencing their mechanical properties. Recent studies have shown that physically stable thin film metallic glasses can have high strength and plasticity, although they may differ from bulk metallic glasses. This study utilized two different fabrication methods to create compositionally similar Zr-based glasses in thin film and bulk form, and characterized their oxygen concentration, composition, and structure. The mechanical response of both types of glasses was examined and found that the thin film metallic glass exhibited higher strength without sacrificing plasticity, with the deformation mechanism changing at elevated temperatures.
