| Outline of Final Research Achievements |
In the present study, we have fabricated binary Zr-Cu bulk metallic glass (BMG) by using an aerodynamic levitation (ADL) technique. In adition, we have investigated the influence of oxygen content on the glass-forming ability (GFA) of Zr-Cu alloys in the containerless solidification process. The critical cooling rate for producing BMG by containerless processing was reduced when the oxygen content increased. To obtain more insight into the GFA of Zr-Cu BMGs, we conducted in-situ synchrotron x-ray diffraction experiments during containerless processing using the ADL technique.
