Patent number: 10589349Abstract: 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.Type: GrantFiled: March 30, 2016Date of Patent: March 17, 2020Assignees: Glassimetal Technology, Inc., Apple Inc.Inventors: Marios D. Demetriou, Joseph P. Schramm, Georg Kaltenboeck, William L. Johnson

Patent number: 9349520Abstract: Ferromagnetic cores made from amorphous glasses and methods of forming ferromagnetic cores from metallic glasses are provided. The method forms a magnetic core from a section of a series of concentrically nested ferromagnetic tubes formed of an amorphous metallic material having a Curie-point temperature above room temperature and demonstrating soft ferromagnetic properties, thereby simplifying the manufacturing process and improving the electrical and mechanical performance of the core itself.Type: GrantFiled: November 9, 2011Date of Patent: May 24, 2016Assignee: California Institute of TechnologyInventors: Marios D.

Patent number: 9297058Abstract: An apparatus and method of uniformly heating, softening, and thermoplastically forming magnetic metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool are provided. 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 material and the equilibrium melting point of the alloy in a time scale of several milliseconds or less. Once the sample is uniformly heated such that the entire sample block has a sufficiently low process viscosity it may be shaped into high quality amorphous bulk articles via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, sheet forming, and blow molding in a time frame of less than 1 second.Type: GrantFiled: February 15, 2012Date of Patent: March 29, 2016Assignee: California Institute of TechnologyInventors: Marios D. Demetriou, Joseph P. Schramm, Georg Kaltenboeck, William L. Johnson
