Recent advances on structural regulation and toughening of 3D printed bulk metallic glasses
Abstract
<p indent="0mm">Bulk metallic glasses (BMGs), a novel class of materials, have garnered significant attention due to their exceptional physical, chemical, and mechanical properties. However, their application as structural materials is limited by challenges in forming and manufacturing. Addressing these issues is essential for expanding their use. Recent advancements in 3D printing technology present promising solutions, making this area a focal point of research. This study systematically reviews recent developments in 3D-printed bulk metallic glasses, emphasizing forming techniques, structural characteristics, and mechanical properties. We explore strategies for structural regulation and toughening, detailing how methods such as defect engineering, the addition of ductile phases, gradient structures, and phase transformation effects influence the mechanical properties of 3D-printed BMGs. Finally, we address current challenges in the field and discuss potential future development trends.</p>
