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.
Claims23
A device comprising:
- a 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;
- wherein the stage is configured to spin at a speed sufficient to spread the BMG in a molten state on the stage to form a solid BMG sheet.
A method of forming a solid BMG sheet, comprising:
- disposing BMG in a molten state onto a stage;
- spreading the BMG in a molten state into the BMG sheet by spinning the stage;
- cooling the BMG in a molten state to form the solid BMG sheet.
A device comprising:
- a stage configured to spread BMG in a molten state into a sheet by centrifugal force, configured to prevent oxidation or contamination of the BMG in a molten state during spreading, and configured to cool the BMG in a molten state into BMG in a solid form while maintain amorphicity of the BMG in a solid state.
