Abstract
Systems and methods to fabricate objects including metallic glass-based materials using low-pressure casting techniques are described. In one embodiment, a method of fabricating an object that includes a metallic glass-based material includes: introducing molten alloy into a mold cavity defined by a mold using a low enough pressure such that the molten alloy does not conform to features of the mold cavity that are smaller than 100 μm; and cooling the molten alloy such that it solidifies, the solid including a metallic glass-based material.
Claims24
A method of fabricating an object that includes a metallic glass-based material comprising:
- introducing a molten metallic glass forming alloy into a mold cavity defined by a mold body having one or more mold features wherein at least one mold feature has a feature size of less than 100 μm under a pressure selected such that the molten metallic glass forming alloy does not conform to the at least one mold feature of the mold cavity smaller than 100 μm;
- and
- cooling the molten metallic glass forming alloy such that it solidifies to form a solid comprising a metallic glass-based material.
A method of fabricating an object that includes a metallic glass-based material comprising:
- introducing molten metallic glass forming alloy into a mold cavity defined by a mold body having one or more mold features wherein at least one mold feature has a feature size of less than 100 μm using a pressure of less than approximately 100 psi such that the molten metallic glass forming alloy does not conform to the at least one mold feature of the mold cavity smaller than 100 μm;
- and
- cooling the molten metallic glass forming alloy at a rate such that the metallic glass forming alloy develops an amorphous structure and solidifies to form a solid comprising a metallic glass-based material.
A method of fabricating an object that includes a metallic glass-based material comprising:
- introducing a molten alloy into a mold cavity defined by a mold having one or more mold features wherein at least one mold feature has a feature size of less than 100 μm under a pressure selected such that the molten alloy does not conform to the at least one mold feature of the mold cavity smaller than 100 μm;
- and
- cooling the molten alloy such that it solidifies to form a solid, wherein the entirety of the solid comprises a metallic glass-based material.
