Imprinting bulk amorphous alloys at room temperature

Patent Lee, Min Ha; Park, Eun Soo; Ott, Ryan Timothy; ...

A technique is disclosed for straining an amorphous alloy at ambient temperature to plastically and homogeneously deform the amorphous alloy, such that at least an exterior surface of the deformed amorphous alloy is substantially free of shear bands. An amorphous alloy may be strained at a rate of less than about 9×10−5 s−1 or by multiple passes of cold rolling. A pattern from a die may be imprinted into the amorphous alloy when strained, and the amorphous alloy may be used as a die to plastically strain other materials.

Method of casting articles of a bulk-solidifying amorphous alloy

Patent Lin, Xianghong [Laguna Niguel, CA]; Johnson, William L [Pasadena, CA]; Peker, Atakan [Aliso Viejo, CA]

A casting charge of a bulk-solidifying amorphous alloy is cast into a mold from a temperature greater than its crystallized melting temperature, and permitted to solidify to form an article. The oxygen content of the casting charge is limited to an operable level, as excessively high oxygen contents produce premature crystallization during the casting operation. During melting, the casting charge is preferably heated to a temperature above a threshold temperature to eliminate heterogeneous crystallization nucleation sites within the casting charge. The casting charge may be cast from above the threshold temperature, or it may be cooled to the casting temperaturemore » « less
