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: Methods for manufacturing cast titanium helmets include casting a helmet in an oversized mold. The resulting oversized cast helmet is then exposed to a hot isostatic press (HIP) process that applies heat and pressure for a predetermined period of time. The resulting oversized cast helmet is then exposed to an acid bath that chemically mills the helmet to a desired thickness and removes contaminants formed during casting of titanium.

Abstract: A forging tool for precision forging of components of intermetallic or high-temperature stable phases with high yield stresses and shapeable at temperatures up to 1400° C. is made of graphite with a low-melting metal or a low-melting metal alloy infiltrated into its open-pored cavities, where metal carbides are created by heat treatment and form with the graphite a two-phase material hardened by subsequent quenching. The tool features high strength thanks to the yield stress increasing as the temperature increases at forging temperatures up to 1400° C., and is oxidation-resistant. It is electrically conductive, and has a low heat capacity, so that rapid inductive heating of the tool involving only low energy expenditure, short forging cycles and an inexpensive isothermic shaping process are possible. It has good lubrication properties, low wear and low manufacturing costs.
