摘要： An apparatus and method of uniformly heating, rheologically 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.

摘要： A method of forming bulk metallic glass engineering materials, and more particularly a method for forming coarsening microstructures within said engineering materials is provided. Specifically, the method forms 'designed composites' by introducing 'soft' elastic/plastic inhomogeneities in a metallic glass matrix to initiate local shear banding around the inhomogeneity, and matching of microstructural length scales (for example, L and S) to the characteristic length scale Rp (for plastic shielding of an opening crack tip) to limit shear band extension, suppress shear band opening, and avoid crack development.

摘要： To identify and manufacture metallic glass forming alloys, large inertial forces or 'g'-forces are used to sequentially separate crystalline phases (particles) as they sequentially form and grow in a molten alloy during gradual cooling of the alloy below its liquidus temperature. These forces physically remove and isolate the actual crystalline particles from the remaining liquid as they are formed. Under the influence of a large g-force, this is accomplished by rapid and efficient sedimentation and stratification. Further contamination and nascent solid 'debris' in the form of oxides, carbides, or other foreign particles can be removed from the molten alloy using the same sedimentation/stratification technique. Finally, a method of efficiently cooling and solidifying the final low melting stratified and decontaminated liquid into a solid glass component is proposed which utilizes convective heat transport by a cooling gas. The result is a vitrified bulk metallic glass component of near net shape.

摘要： A manufacturing process for casting amorphous metallic parts separates the filling and quenching steps of the casting process in time. The mold is heated to an elevated casting temperature at which the metallic alloy has high fluidity. The alloy fills the mold at the casting temperature, thereby enabling the alloy to effectively fill the spaces of the mold. The mold and the alloy are then quenched together, the quenching occurring before the onset of crystallization in the alloy. With this process, compared to conventional techniques, amorphous metallic parts with higher aspect ratios can be prepared.
