Abstract: Described herein is a method of combining discrete pieces of BMG in to a BMG feedstock that has at least one dimension greater than a critical dimension of the BMG, by methods such as thermoplastic forming, pressing, extruding, folding or forging. Other embodiments relate to a bulk metallic glass (BMG) component or feedstock having discrete pieces of a BMG, wherein the BMG component or feedstock has at least one dimension greater than a critical dimension of the BMG.

Abstract: Described herein is a feedstock including a core comprising BMG and a sheath attached the core. The sheath has a different physical property, a different chemical property or both from the core. Alternatively, the feedstock can include a sheath that encloses one or more core comprising BMG. The feedstock can be manufactured by attaching the sheath to the core, shot peening the core, etching the core, ion implanting the core, or applying a coating to the core, etc. The feedstock can be used to make a part by injection molding. The sheath can be used to adjust the composition of the core to reach the composition of the part.

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 is a vacuum mold with at least a first plate and a second plate to mold materials (e.g., amorphous alloys), and a method for manufacturing parts using the mold. An ejector mechanism, to eject molded material, is enclosed within an ejector box that is vacuum sealed relative to the plates. An ejector rod for moving the mechanism is also vacuum sealed via a seal in a vacuum feed through opening. Seals are provided between adjacent interfaces of the mold parts (plates and ejector box) to vacuum seal the mold. The mold is connected to at least one vacuum source that applies vacuum pressure thereto via a first vacuum port in a first direction. A second vacuum port may also be provided to apply pressure in a second direction. A vacuum release valve may be connected to the mold to release vacuum pressure applied to the mold.

Abstract: One embodiment provides a composition, the composition comprising: an alloy that is at least partially amorphous and is represented by a chemical formula: (Zr, Ti)aMbNcSnd, wherein: M is at least one transition metal element; N is Al, Be, or both; a, b, c, and d each independently represents an atomic percentage; and a is from about 30 to 70, b is from about 25 to 60, c is from about 5 to 30, and d is from about 0.1 to 5.

Abstract: Disclosed is a temperature regulated vessel, and method for using the same, having a body configured to melt meltable material received therein, and one or more temperature regulating lines within the body configured to flow a liquid therein for regulating a temperature of the meltable material received in the melting portion. The vessel has a poor or low thermally conductive material on one or more of its parts, such as on the melting portion, on exterior surfaces of the body, and/or surrounding the temperature regulating lines to increase melt temperature of the material. The melting portion can also have indentations in its surface, and low thermally conductive material can be provided in the indentations. The vessel can be used to melt amorphous alloys, for example.
