Summary: Research efforts have been made to overcome the difficulties in manufacturing bulk metallic glasses (BMGs) in recent years. Additive manufacturing methods such as selective laser melting (SLM) have shown promise in overcoming the limitations of traditional fabrication methods, allowing for the production of complex structures with superior properties. This review discusses the current status, challenges, and prospects of using SLM technology to prepare BMGs, highlighting the need to address key issues in this field for future applications as both structural and functional materials.

Summary: Monolithic bulk metallic glass and glass matrix composites with a relative density above 98% were produced by selective laser melting of Cu46Zr46Al8(at.%). The addition of B2 CuZr nanocrystals increased structural heterogeneity, affecting the mechanical properties of the materials. Despite the presence of crystals and high overall free volume content, all additively manufactured samples failed at lower stress than the as-cast glass due to increased brittleness caused by relatively large pores and higher oxygen content after selective laser melting.

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: This review summarizes the latest progress in the field of laser powder bed fusion (LPBF) additively manufactured bulk metallic glasses (BMGs), focusing on their mechanical properties. The review discusses the BMG alloy systems that have been additively manufactured using LPBF, and clarifies the mechanical properties of LPBF-fabricated BMGs, including micro- and nano-hardness, micropillar compressive performance, and macro-compressive and tensile performance. The relationship between the mechanical properties and microstructure of LPBF-produced BMGs is also analyzed. Measures for improving the mechanical properties of LPBF-fabricated BMGs are discussed.

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: In this study, Fe-based bulk metallic glass was successfully produced using selective laser melting, with optimized parameters resulting in high relative density and amorphous rate samples. The analysis revealed the presence of various crystalline phases in the heat affected zone, and heat treatment was utilized to study the crystallization behavior of the amorphous phase. Variation in hardness was observed among different grain regions, with the highest hardness found in the amorphous phase.

Summary: This study explores the polarized plastic response of metallic glasses induced by asymmetric mechanical cycling. The results show that the amplitude of mechanical cycling can control the anelastic limit, and the plastic rearrangements exhaust while the anelastic rearrangements govern the anisotropy. The polarized plastic response is originated from the asymmetry of the local potential energy surface.

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: 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: A Zr55Cu30Al10Ni5 bulk metallic glass composite (BMGC) was fabricated using selective laser melting (SLM) with argon gas atomized powder. The microstructure and tensile deformation behavior of SLMed Zr55 BMGCs were studied, revealing a periodic microstructure with three different zones and a stepwise tensile fracture behavior. Nanoindentation tests showed that the nanocrystal + amorphous crystalline zone had lower hardness and elastic modulus, resulting in a significant stress drop after the failure of the hard amorphous layers. This study further confirmed the feasibility of SLM technology for developing high-performance BMGCs for industrial applications.
