Abstract
Systems and methods in accordance with embodiments of the invention fabricate objects including metallic glass-based materials using ultrasonic welding. In one embodiment, a method of fabricating an object that includes a metallic glass-based material includes: ultrasonically welding at least one ribbon to a surface; where at least one ribbon that is ultrasonically welded to a surface has a thickness of less than approximately 150 μm; and where at least one ribbon that is ultrasonically welded to a surface includes a metallic glass-based material.
Claims26
A method of fabricating an object that includes a metallic glass-based material comprising:
- ultrasonically welding a first ribbon to a surface;
- ultrasonically welding at least a second ribbon to a surface;
- wherein at least the first ribbon or the second ribbon has a thickness of less than approximately 150 μm;
- and
- wherein at least the first ribbon or the second ribbon comprises a metallic glass-based material;
- wherein each of the first ribbon and the at least second ribbon conforms to a geometry that is entirely defined by a flat face extruded through a thickness;
- wherein the ultrasonic welding of at least one ribbon to a surface results in the bonding of the majority of the surface area of the respective flat face to the surface;
- and
- wherein the ribbons ultrasonically welded to respective surfaces collectively define a desired shape in the object to be fabricated.
