Abstract: Embodiments herein relate to a method for forming a bulk solidifying amorphous alloy sheets have different surface finish including a “fire” polish surface like that of a float glass. In one embodiment, a first molten metal alloy is poured on a second molten metal of higher density in a float chamber to form a sheet of the first molten that floats on the second molten metal and cooled to form a bulk solidifying amorphous alloy sheet. In another embodiment, a molten metal is poured on a conveyor conveying the sheet of the first molten metal on a conveyor and cooled to form a bulk solidifying amorphous alloy sheet. The cooling rate such that a time-temperature profile during the cooling does not traverse through a region bounding a crystalline region of the metal alloy in a time-temperature-transformation (TTT) diagram.

Abstract: Disclosed is a vessel for melting meltable material having a body with a melting portion configured to receive meltable material to be melted therein and an injection path for injecting the meltable material in molten form after melting (e.g., into a mold). The body has a recess configured to contain the meltable material within the vessel during melting of the material. The vessel is configured for movement between in a first position to restrict entry of molten material into an injection path of the vessel and to contain the material in the recess during melting, and a second position to allow movement of the material in a molten form through the injection path and into the mold (e.g., using a plunger). The vessel can be used in an injection molding system for molding bulk amorphous alloys.

Abstract: Described herein is a feedstock comprising BMG. The feedstock has a surface with an average roughness of at least 200 microns. Also described herein is a feedstock comprising BMG. The feedstock, when supported on a support during a melting process of the feedstock, has a contact area between the feedstock and the support up to 50% of a total area of the support. These feedstocks can be made by molding ingots of BMG into a mole with surface patterns, enclosing one or more cores into a sheath with a roughened surface, chemical etching, laser ablating, machining, grinding, sandblasting, or shot peening. The feedstocks can be used as starting materials in an injection molding process.
