Abstract
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.
Claims13
A method of manufacturing a gearbox housing comprising:
- selecting an alloy composition from which the gearbox housing will be fabricated, wherein the alloy composition is configured to form, when cast, a metallic glass-based material characterized by:
- a Young's modulus of less than 110 GPa,
- a fracture toughness of between 20 MPa m1/2 and approximately 200 MPa m1/2,
- a Rockwell C hardness of greater than 45,
- an elastic limit of greater than 1%, and
- a solidification shrinkage of less than 1.5;
- casting the alloy composition around a solid body so as to form a cast part formed of the metallic glass-based material and characterized by a cavity disposed therein and defined by an outer contour of the solid body;
- wherein the cast part is further characterized by a plurality of gear teeth disposed about an inner lining of the cavity;
- and
- nondestructively separating the cast part from the solid body.
