“…Selective laser melting (SLM) is a branch of additive manufacturing, which is used for the formation of disordered solids [120][121][122] and does not require precise molds for the fabrication of complex and large-scale parts [123]. For example, SLM has been used to fabricate metallicglass systems, which has been found to be beneficial as a composite matrix for biomedical applications [124,125].…”

Materials with a disordered atomic structure, often termed glassy materials, are the focus of extensive research due to the possibility of achieving remarkable mechanical, electrochemical, and magnetic properties compared to crystalline materials. The glassy materials are observed to have an improved elastic modulus combined with a higher strength and hardness. Moreover, better corrosion resistance in different mediums is also observed for glassy solids, which is difficult to attain using conventional crystalline materials. As a result, the potential applications of metallic-glass systems are continually increasing. Amorphous materials are usually divided into two categories based upon their size. Materials with a thickness and diameter larger than the millimeter (mm) scale are termed as bulk metallic glass (BMG). However, the brittle nature of the bulk-sized samples restricts the size of metallic-glass systems to the micron (µm) or nanometer (nm) range. Metallic glasses with a specimen size in the scale of either µm or nm are defined as thin-film metallic glass (TFMG). In this review, BMGs and TFMGs are termed as metallic glass or MG. A large number of multi-component MGs and their compositional libraries reported by different research groups are summarized in this review. The formation of a multicomponent metallic glass depends on the constituent elements and the fabrication methods. To date, different unique fabrication routes have been adopted to fabricate BMG and TFMGs systems. An overview of the formation principles and fabrication methods as well as advantages and limitations of conventional MG fabrication techniques is also presented. Furthermore, an in-depth analysis of MG inherent properties, such as glass forming ability, and structural, mechanical, thermal, magnetic, and electrochemical properties, and a survey of their potential applications are also described.

The aim of this study is to fabricate Zr-based bulk metallic glass matrix composites (BMG-MCs) for biomedical usage and subject them to a comprehensive and farreaching analysis with respect to their mechanical properties, biocorrosion resistance, biocompatibility, and interactions with biofilms that all may arise from their chemical compositions and unusual disordered internal structure. In this study, we fabricate Zr40Ti15Cu10Ni10Be25, Zr50Ti15Cu10Ni10Be25, and Zr40Ti15Cu10Ni5Si5Be25 alloys and confirm their glassy matrix nature through differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) analyses. The mechanical properties, assessed via nanoindentation, demonstrate the high hardness, strength, and elasticity of the produced materials. Corrosion resistance is investigated in simulated body fluid, with Zr-based BMG-MCs exhibiting superior performance compared to conventional biomedical materials, including 316L stainless steel and Ti6Al4V alloy. Biocompatibility is assessed using human fetal osteoblastic cell line hFOB 1.19, revealing low levels of cytotoxicity. The study also examines the potential for biofilm formation, a critical factor in the success of biomedical implantation, where bacterial infection is a major concern. Our findings suggest, as never reported before, that Zr-based BMG-MCs, with their unique composite glassy structure and excellent physicochemical properties, are promising candidates for various biomedical applications, potentially offering improved performance over traditional metallic biomaterials.

This paper investigates the additive manufacturing route for a novel glass-forming titanium-based sulfur-containing alloy of the composition $${\text{Ti}}_{60} {\text{Zr}}_{15} {\text{Cu}}_{17} {\text{S}}_{8}$$ Ti 60 Zr 15 Cu 17 S 8 . This system is a promising candidate for medical devices since the lack of toxic components is combined with a high corrosion resistance and strength. Preliminary experiments and simulations show a general processability of bulk material by powder bed fusion technologies. TEM and XRD reveal an amorphous microstructure of laser-treated surfaces. Ultrasonic atomization is used to fabricate a flowable powder feed stock with spherical morphology and crystalline microstructure, which is suitable for processing in powder bed fusion. Correlations between detected crystalline phase formations and melt pool dynamics are revealed by SEM and EDX. It is shown that bulk samples with a high relative density and partially crystalline microstructure can be manufactured.
