摘要：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.
