A review of bulk metallic glasses by selective laser melting
Bulk metallic glasses (BMGs) are a subject of interest due to their superior specific properties. However, BMGs are difficult to apply in industry due to their difficulty in manufacturing and secondary operation. Selective laser melting (SLM) can obtain relatively high cooling rates during the ‘layer-by-layer’ process. The main problems in SLM additive fabrication of amorphous alloys are cracks and crystallization. In this paper, based on the research of SLM additive manufacturing BMGs in recent years, the factors affecting crystallization and forming are discussed from many aspects according to different material systems. In addition, the mechanical, physical and chemical properties of BMGs are reviewed. Finally, the prospect of SLM in additive manufacturing of BMGs is provided.
