Abstract
Disclosed herein is a device comprising: vacuum chamber; a stage configured to receive BMG in a molten state or a BMG feedstock, configured to spin, and located in the vacuum chamber; a heater configured to melt the BMG feedstock or to keep BMG in a molten state molten; wherein the stage comprises one or more conduits therein and the conduits are configured to accommodate a cooling fluid. Also disclosed herein is a method of forming a solid BMG sheet, the method comprising: disposing BMG in a molten state onto a stage; spreading the BMG in a molten state into a sheet of BMG in a molten state by spinning the stage; cooling the sheet of BMG in a molten state to form a solid BMG sheet.
Claims20
A method of forming a solid bulk metallic glass (BMG) sheet, comprising:
- disposing molten BMG onto a stage;
- spinning the stage to spread the molten BMG;
- and
- cooling the molten BMG to form a solid BMG sheet.
A method of forming a component comprising a bulk metallic glass (BMG), comprising:
- disposing a substrate onto a stage;
- disposing molten BMG onto the substrate;
- and
- spinning the stage to spread the molten BMG over a surface of the substrate.
A method of forming a solid bulk metallic glass (BMG) sheet, comprising:
- disposing a BMG feedstock on a stage;
- activating a heater associated with the stage to melt the BMG feedstock, thereby forming a molten BMG;
- spinning the stage to spread the molten BMG;
- and
- flowing a fluid through a conduit to cool the molten BMG, thereby forming a solid BMG sheet.
