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: Various embodiments provide apparatus and methods for melting materials and for containing the molten materials within melt zone during melting. Exemplary apparatus may include a vessel configured to receive a material for melting therein; a load induction coil positioned adjacent to the vessel to melt the material therein; and a containment induction coil positioned in line with the load induction coil. The material in the vessel can be heated by operating the load induction coil at a first RF frequency to form a molten material. The containment induction coil can be operated at a second RF frequency to contain the molten material within the load induction coil. Once the desired temperature is achieved and maintained for the molten material, operation of the containment induction coil can be stopped and the molten material can be ejected from the vessel into a mold through an ejection path.

Abstract: Various embodiments provide systems and methods for casting amorphous alloys. Exemplary casting system may include an insertable and rotatable vessel configured in a non-movable induction heating structure for melting amorphous alloys to form molten materials in the vessel. While the molten materials remain heated, the vessel may be rotated to pour the molten materials into a casting device for casting them into articles.

Abstract: The embodiments described herein relate to methods and apparatus for counter-gravity formation of BMG-containing hollow parts. In one embodiment, the BMG-containing hollow parts may be formed by first feeding a molten metal alloy in a counter-gravity direction into a mold cavity to deposit the molten metal alloy on a surface of the mold cavity and then solidifying the deposited molten metal alloy.
