US Classification:

164479, 164463, 164 81

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:

Described herein is a feedstock comprising BMG. The feedstock has a surface with an average roughness of at least 200 microns. Also described herein is a feedstock comprising BMG. The feedstock, when supported on a support during a melting process of the feedstock, has a contact area between the feedstock and the support up to 50% of a total area of the support. These feedstocks can be made by molding ingots of BMG into a mole with surface patterns, enclosing one or more cores into a sheath with a roughened surface, chemical etching, laser ablating, machining, grinding, sandblasting, or shot peening. The feedstocks can be used as starting materials in an injection molding process.

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:

Described herein are methods of constructing a part using BMG layer by layer. In one embodiment, a layer of BMG powder 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 layers of non-BMG can be used as needed. In one embodiment, layers of BMG can be cut from one or more sheets of BMG to desired shapes, stacked and fused to form the part.

Abstract:

Embodiments herein relate to a method of making roll formed objects of a bulk solidifying amorphous alloy comprising a metal alloy, and articles thereof. The roll forming includes forming a portion of the bulk solidifying amorphous alloy at a temperature greater than a glass transition temperature (Tg) of the metal alloy. The roll forming is done such that a time-temperature profile of the portion during the roll forming does not traverse through a region bounding a crystalline region of the metal alloy in a time-temperature-transformation (TTT) diagram of the metal alloy.
