Methods of melting and introducing amorphous alloy feedstock for casting or processing

摘要

Various embodiments provide apparatus and methods for melting and introducing alloy feedstock for molding by using a hollow branch having a constraint mechanism therein. In one embodiment, a hollow branch can extend upward from a cold chamber that is substantially horizontally configured. The hollow branch including a constraint mechanism can be capable of containing an alloy feedstock for melting into the molten alloy in the hollow branch and introducing the molten alloy to the cold chamber for molding.

1. A method comprising molding a molten alloy into a BMG part in an apparatus comprising:
a cold chamber substantially horizontally configured and connected to a mold configured for molding the molten alloy into the BMG part; and a hollow branch extending upward from a region of the cold chamber having an upward angle with a horizontal axis, the hollow branch comprising a constraint mechanism capable of containing both a solid alloy feedstock during melting into the molten alloy in the hollow branch and the molten alloy prior to introducing the molten alloy to the cold chamber for molding; wherein an interface between the constraint mechanism and the molten alloy is substantially non-wetting to the molten alloy, wherein the constraint mechanism is configured to be cooled by a coolant to cool the constraint mechanism to regulate a temperature of the interface.
