Abstract

The fabrication of open-cell bulk metalli glasses (BMG) foams was analyzed and high compressive ductility achieved by the amorphous metallic foams through strut bending was demonstrated. Optical-grade BaF₂ was crushed in a mortar and pestle, sieved to isolate 212-250 μm particles, and sintered into patterns for 10 h at 1250°C under high vacuum. Patterns of 7 mm diameter were placed within thin-walled stainless steel crucibles and vacuum dried at 300°C for 30 minutes in a tube furnace. The results show that while the ductility of aluminum struts does not depend on deformation mode, that of Vit106 struts is limited to bending deformation.
