    摘要: Nanostructured materials that contain amorphous intergranular films (AlFs) are described herein. Amorphous intergranular films are structurally disordered (lacking the ordered pattern of a crystal) films that are up to a few nanometers thick. Nanostructured materials containing these films exhibit increased ductility, strength, and thermal stability simultaneously. A nanocrystalline material system that has two or more elements can be designed to contain AlFs at the grain boundaries, provided that the dopants segregate to the interface and certain materials science design rules are followed. An example of AlFs in a nanostructured Cu—Zr alloy is provided to illustrate the benefits of integrating AlFs into nanostructured materials.

    摘要: The disclosure is directed to freefall methods and apparatuses for preparation of amorphous BMG feedstock and sheet material. In certain aspects, the disclosure relates to methods and apparatuses for contactless formation of BMG feedstock and sheet material via a drop-tower. In certain embodiments, the methods comprise releasing droplets of molten amorphous alloy into a cooled, pressurized chamber of a drop-tower, wherein the droplets traverse the chamber through freefall to thereby form BMG feedstock or sheet material.

    摘要: 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.
