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.
