    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 are systems and methods for mechanically reducing an amount of the skull material in a finished, molded part formed from amorphous alloy using an injection molding system. Skull material of molten amorphous alloy can be captured in a trap before molding such material. A cavity can be provided in the injection molding system to trap the skull material. For example, the cavity can be provided in the mold, the tip of the plunger rod, or in the transfer sleeve. Alternatively, mixing of molten amorphous alloy can be induced so that skull material is reduced before molding. A plunger and/or its tip can be used to induce mixing (e.g., systematic movement of plunger rod, or a shape of its tip). By minimizing the amount of skull material in the finished, molded part, the quality of the part is increased.

    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: Embodiments herein relate to a process for semi-continuous or continuous production of a solid object from a molten metal, with the potential of being a cleaner and less expensive alternative to complicated split mold processes currently used. The embodiments can be used to perform multiple melt/pour cycles without breaking vacuum, with the system only opened to remove the solid object via an air lock, e.g., a separate chamber or load lock, which will be periodically opened to remove feedstock without breaking the vacuum of the process chamber. Embodiments also relate to an apparatus for semi-continuous or continuous production of a solid object from a molten metal.

    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.
