摘要： A rapid discharge heating and forming apparatus is provided. The apparatus includes a source of electrical energy and at least two electrodes configured to interconnect the source of electrical energy to a metallic glass sample. The apparatus also includes a shaping tool disposed in forming relation to the metallic glass sample. The source of electrical energy and the at least two electrodes are configured to deliver a quantum of electrical energy to the metallic glass sample to heat the metallic glass sample. The shaping tool is configured to apply a deformational force to shape the heated sample to an article. The at least two electrodes have a yield strength of at least 200 MPa, a Young's modulus that is at least 25% higher than the metallic glass sample, and an electrical resistivity that is lower than the metallic glass sample by a factor of at least 3.

摘要： The disclosure is directed to a method of forming high-aspect-ratio metallic glass articles that are substantially free of defects and cosmetic flaws by means of rapid capacitive discharge forming. Metallic glass alloys that are stable against crystallization for at least 100 ms at temperatures where the viscosity is in the range of 100 to 104 Pa-s are considered as suitable for forming such high-aspect-ratio articles.

摘要： An automated rapid capacitive discharge apparatus is provided for sequentially or simultaneously rapidly heating and shaping a plurality of metallic glass feedstock samples. The apparatus includes a sample feeder defining a body for holding a plurality of samples and being capable of sequentially positioning at least one feedstock sample into a discharge position within the processing compartment. In the processing compartment the sample is heated by a discharge of a quantum of electrical energy supplied via electrodes, then shaped into a desired shape by means of a shaping tool, and subsequently moved out of the discharge position as a second feedstock moves into a discharge position.

摘要： The present disclosure is directed to a method of physically separating and electrically isolating the chamber where the ohmic heating of the feedstock occurs by delivering current through the electrodes (heating barrel), from the chamber where the feedstock deformation and flow through the runner takes place by the motion of the plungers (forming barrel). The method also includes transferring the feedstock from the heating barrel to the forming barrel between the heating and the forming processes at a high enough rate such that negligible cooling and no substantial crystallization of the feedstock occurs during the transfer.

摘要： Methods and apparatus for forming high aspect ratio metallic glass objects, including metallic glass sheets and tubes, by a melt deposition process are provided. In some methods and apparatus a molten alloy is deposited inside a channel formed by two substrates moving relative to each other, and shaped and quenched by conduction to the substrates in a manner that enables the molten alloy to vitrify without undergoing substantial shear flow.

摘要： Methods and apparatus for forming high aspect ratio metallic glass, including metallic glass sheet and tube, by a melt deposition process are provided. In some methods and apparatus a molten alloy is deposited inside a tubular channel formed by two concentrically arranged substrates, and shaped and quenched by conduction to the substrates in a manner that enables the molten alloy to vitrify prior to undergoing substantial shear flow. The deposition method allows the molten alloy to be deposited and formed while being quenched, without undergoing substantial shear flow.
