摘要： A method of thermomagnetically processing a material includes disposing a workpiece within a bore of a magnet; exposing the workpiece to a magnetic field of at least about 1 Tesla generated by the magnet; and, while exposing the workpiece to the magnetic field, applying heat energy to the workpiece at a plurality of frequencies to achieve spatially-controlled heating of the workpiece. An apparatus for thermomagnetically processing a material comprises: a high field strength magnet having a bore extending therethrough for insertion of a workpiece therein; and an energy source disposed adjacent to an entrance to the bore. The energy source is an emitter of variable frequency heat energy, and the bore comprises a waveguide for propagation of the variable frequency heat energy from the energy source to the workpiece.

摘要： A method of thermomagnetically processing an aluminum alloy entails heat treating an aluminum alloy, and applying a high field strength magnetic field of at least about 2 Tesla to the aluminum alloy during the heat treating. The heat treating and the application of the high field strength magnetic field are carried out for a treatment time sufficient to achieve a predetermined standard strength of the aluminum alloy, and the treatment time is reduced by at least about 50% compared to heat treating the aluminum alloy without the magnetic field.

摘要： An apparatus for dispersing particles within a molten material in a mold-less casting process comprises a primary electromagnet for generating an AC magnetic field and a secondary electromagnet adjacent to the primary electromagnet for generating an independent DC magnetic field. Each of the primary and secondary electromagnets comprises a coil and at least one of the electromagnets is positioned about a common longitudinal axis. A heat source may be positioned at a first end of the common longitudinal axis for forming a melt to be exposed to the AC and DC magnetic fields, and a particle injection device is positioned at one or more positions about the common longitudinal axis for injecting particles into the melt during magnetic field exposure. The apparatus does not include a solid body for containing the melt prior to solidification.
