Patent number: 11920668Abstract: Systems and methods in accordance with embodiments of the invention implement bulk metallic glass-based macroscale gears. In one embodiment, a method of fabricating a bulk metallic glass-based macroscale gear, where at least either the thickness of the gear is greater than 3 mm or the diameter of the gear is greater than 9 mm, includes: obtaining design parameters of the gear to be formed; selecting a bulk metallic glass from which the gear will be formed based on the obtained design parameters, where the selected bulk metallic glass is characterized by a resistance to standard modes of wear and a resistance to brittle fracture such that a gear can be formed from the selected bulk metallic glass that accords with the obtained design parameters; and fabricating the gear from the selected bulk metallic glass that accords with the obtained design parameters.Type: GrantFiled: March 5, 2021Date of Patent: March 5, 2024Assignee: California Institute of TechnologyInventors: Douglas C Hofmann, Andrew Kennett, Kobie T. Boykins

Patent number: 10487934Abstract: Systems and methods in accordance with embodiments of the invention efficaciously implement robust gearbox housings. In one embodiment, a method of fabricating a gearbox housing includes: providing an alloy composition from which the gearbox housing will be fabricated from; casting the alloy composition around a solid body so as to form a part characterized by the inclusion of a cavity, where the cast part includes a metallic glass-based material; and nondestructively separating the cast part from the solid body.Type: GrantFiled: December 16, 2015Date of Patent: November 26, 2019Assignee: California Institute of TechnologyInventors: Andrew Kennett, Douglas C. Hofmann, John Paul C. Borgonia
