摘要： The present invention relates to materials, methods and apparatuses for performing imprint lithography using amorphous metallic materials. The amorphous metallic materials can be employed as imprint media and thermoplastic forming processes are applied during the pattern transfer procedure to produce micron scale and nanoscale patterns in the amorphous metallic layer. The pattern transfer is in the form of direct mask embossing or through a serial nano-indentation process. A rewriting process is also disclosed, which involves an erasing mechanism that is accomplished by means of a second thermoplastic forming process. The amorphous metallic materials may also be used directly as an embossing mold in imprint lithography to allow high volume imprint nano-manufacturing. This invention also comprises of a method of smoothening surfaces under the action of the surface tension alone.

摘要： A very low pressure gas or blow forming process for shaping a bulk metallic glass (BMG) in its supercooled liquid state that avoids the fractional stick forces experienced by conventional shaping techniques by engineering the expansion of a pre-shape or parison of BMG material such that substantially all of the lateral strain required to form the final article is accomplished prior to the outer surface of the parison contacting the surface of the shaping apparatus is provided. The capability offered by the inventive shaping process to avoid the frictional forces exerted by the shaping apparatus surface allows for the formation of precision net-shape complex multi-scale parts and components using processing conditions inaccessible by conventional processes.

摘要： A class of materials has advantageous utility in electrocatalytic applications, e.g., fuel cells. The materials circumvent conventional Pt-based anode poisoning and the agglomeration/dissolution of supported catalysts during long-term operation by exploiting the unique physical and chemical properties of bulk metallic glass to create nanowires for electrocatalytic applications, e.g., fuel cell and battery applications. These amorphous metals can achieve unusual geometries and shapes along multiple length scales. The absence of crystallites, grain boundaries and dislocations in the amorphous structure of bulk metallic glasses results in a homogeneous and isotropic material down to the atomic scale, which displays very high strength, hardness, elastic strain limit and corrosion resistance. The melting temperatures of the disclosed bulk metallic glasses are much lower than the estimated melting temperatures based on interpolation of the alloy constituents making them attractive as highly malleable materials.
