  • Patent number: 8776566
    Abstract: An apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool in combination with an electromagnetic force generated by the interaction of the applied current with a transverse magnetic field. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample or charge of metallic glass alloy to a predetermined “process temperature” between the glass transition temperature of the amorphous metal and the equilibrium melting point of the alloy in a time scale of several milliseconds or less, at which point the interaction between the electric field and the magnetic field generates a force capable of shaping the heated sample into a high quality amorphous bulk article via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, and blow molding in a time scale of less than one second.

  • Publication number: 20140186648
    Abstract: 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.

An undercut is a beveled edge caused by an etchant attacking an etchable block laterally and optionally vertically. The formed part can be made of a bulk amorphous alloy. In some cases, the etchable block can also be used to form at least one threaded portion in the part.

  • Publication number: 20140007986
    Abstract: A composite structure includes a matrix material having an intrinsic strain-to-failure rating in tension and a reinforcing material embedded in the bulk material. The reinforcing material is pre-stressed by a tensile force acting along one direction. The embedded reinforcing material interacts with the matrix material to place the composite structure into a compressive state. The compressive state provides an increased strain-to-failure rating in tension of the composite structure along a direction that is greater than the intrinsic strain-to-failure rating in tension of the matrix material along that direction. At least one of the matrix material and the reinforcing material is a bulk amorphous alloy (BAA). The reinforcing material can be a fiber or wire. In various embodiments, the matrix material may be a bulk amorphous alloy and/or the reinforcing material may be a bulk amorphous alloy.

    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.
