    摘要: A forging 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 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 forging in a time frame of less than 1 second.

    摘要: Multi-layered cellular metallic glass structures and methods of preparing the same are provided. In one embodiment, the cellular metallic glass structure includes at least one patterned metallic glass sheet and at least one additional sheet. The at least one patterned metallic glass sheet may include multiple sheets connected together to form a group of sheets, and the structure may include a group of sheets sandwiched between two outer sheets. The patterned metallic glass sheets may be patterned by thermoplastically forming two- and/or three-dimensional patterns in the metallic glass sheets. The metallic glass cellular structures are useful in a wide variety of applications, including but not limited to blast protection applications, energy absorption applications, structural support applications, biomedical implant applications, heat exchanger applications, thermal management applications, electrical shielding applications, magnetic shielding applications, and debris and radiation shielding for aerospace and outer space applications.

    摘要: 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.

The inventive iron-based alloy is based on the observation that by very tightly controlling the composition of the metalloid moiety of the Fe-based, P-containing bulk metallic glass alloys it is possible to obtain highly processable alloys with surprisingly low shear modulus and high toughness.
