Abstract
Bulk metallic glasses (BMGs) have attracted increasing attention and tremendous interest owing to their extraordinary mechanical and chemical properties. However, the limited dimensions and simple geometries of the BMGs fabricated by traditional techniques severely restrict their widespread applications. In the present study, a large-size Zr50Ti5Cu27Ni10Al8 (Zr50) BMG is successfully fabricated by laser 3D printing technique. The SEM and XRD results reveal that the microstructure of printed Zr50 BMG consists of both amorphous and crystalline phases. The printed Zr50 alloy possessed high percentage of amorphous phase and dose not crystallize more seriously as the deposited sample becomes thicker.
