    Abstract: Embodiments herein relate to methods and apparatuses for casting of BMG-containing parts. The surfaces of the mold that come into contact with the molten amorphous alloy comprise an amorphous material. In accordance with the disclosure, the mold may be coated with an amorphous material, e.g., to reduce, minimize, or eliminate crystallization of the molded BMG-containing part. The surfaces of the mold are coated, in certain aspects, so as to reduce or eliminate potential grain-boundary nucleation sites for BMG crystallization. The amorphous material may be selected based on the particular molten amorphous alloy to be cast, e.g., based on the wetting properties, the melting and cooling properties, etc.

    Abstract: Described herein are methods of constructing a part using metallic glass-forming alloys, layer by layer, as well as bulk metallic glass-forming materials designed for use therewith. In certain embodiments, a layer of metallic glass-forming alloy powder, wire, or a sheet of metallic glass material is deposited to selected positions and then fused to a layer below by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part, layer by layer. One or more sections or layers of material that is not a metallic glass can be included as needed to form composite parts.

    Abstract: Exemplary embodiments described herein related to methods and systems for casting metal alloys into articles such as BMG articles. In one embodiment, processes involved for storing, pre-treating, alloying, melting, injecting, molding, etc. can be combined as desired and conducted in different chambers. During these processes, each chamber can be independently, separately controlled to have desired chamber environment, e.g., under vacuum, in an inert gas environment, or open to the surrounding environment. Due to the flexible, independent control of each chamber, the casting cycle time can be reduced and the production throughput can be increased. Contaminations of the molten materials and thus the final products are reduced or eliminated.

    Abstract: Various embodiments provide methods and apparatus for forming bulk metallic glass (BMG) articles using a mold having a stationary mold part and a movable mold part paired to form a mold cavity. A molten material can be injected to fill the mold cavity. The molten material can then be cooled into a BMG article at a desired cooling rate. While injecting and/or cooling the molten material, the movement of the movable mold part can be controlled, such that a thermal contact between the molten material and the mold can be maintained. BMG articles can be formed without forming an underfilled part. Additional structural features can be imparted in the BMG article during formation. At least a portion of the formed BMG article can have an aspect ratio (first dimension/second dimension) of at least 10 or less than 0.1.
