摘要： A bulk high performance permanent magnet comprising a neodymium-iron-boron core having an outer surface, and a coercivity-enhancing element residing on at least a portion of said outer surface, with an interior portion of said neodymium-iron-boron core not having said coercivity-enhancing element therein. Also described herein is a method for producing the high-coercivity bulk permanent magnet, the method comprising: (i) depositing a coercivity-enhancing element on at least a portion of an outer surface of a neodymium-iron-boron core substrate to form a coated permanent magnet; and (ii) subjecting the coated permanent magnet to a pulse thermal process that heats said outer surface to a substantially higher temperature than an interior portion of said neodymium-iron-boron core substrate, wherein said substantially higher temperature is at least 200° C. higher than said interior portion and is of sufficient magnitude to induce diffusion of said coercivity-enhancing element below said outer surface but outside of said interior portion.

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： Several examples of additive manufacturing machines and methods for depositing a bead of composite polymer material having continuous fiber reinforcement are disclosed. A length of fiber reinforcement is provided to a nozzle. The fiber reinforcement is embedded into a stream of a base polymer material at the nozzle and deposited as a bead of composite polymer material having fiber reinforcement. The fiber reinforcement may be dry or pre-impregnated with a reinforcing polymer. The additional strength of the composite polymer material having fiber reinforcement allows for true, three-dimensional printing of articles having unsupported regions.

摘要： Particulate matter is dispersed in a fluid material. A sample including a first material in a fluid state and second material comprising particulate matter are placed into a chamber. The second material is spatially dispersed in the first material utilizing EMAT force. The dispersion process continues until spatial distribution of the second material enables the sample to meet a specified criterion. The chamber and/or the sample is electrically conductive. The EMAT force is generated by placing the chamber coaxially within an induction coil driven by an applied alternating current and placing the chamber and induction coil coaxially within a high field magnetic. The EMAT force is coupled to the sample without physical contact to the sample or to the chamber, by another physical object. Batch and continuous processing are utilized. The chamber may be folded within the bore of the magnet. Acoustic force frequency and/or temperature may be controlled.
