    • Various implementations of the invention correspond to an improved vortex flux generator. In some implementations of the invention, the improved vortex flux generator includes a magnetic circuit configured to produce a magnetic field; a quench controller configured to provide a variable current; a vortex material configured to form and subsequently dissipate a vortex in response to the variable current, wherein upon formation of the vortex, a magnetic field density surrounding the vortex is urged to decrease, and wherein upon subsequent dissipation of the vortex, the urging to decrease ceases and the magnetic field density increases prior to a reformation of the vortex, and wherein the decrease of the magnetic field density and the increase of the magnetic field density correspond to a modulation of the magnetic field; an inductor disposed in a vicinity of the vortex such that the modulation of the magnetic field induces an electrical current in the inductor; and a dissipation superconductor electrically disposed in parallel with the vortex material and configured to carry, without quenching, an entirety of the variable current during dissipation of the vortex in the vortex material.

    • A method of producing a Metal Matrix Composite (MMC) with uniform surface layers is disclosed. First, a low volume fraction compressible discontinuous ceramic fiber paper is set on the base of a mold cavity. Next, an array of reinforcement preform(s) (1×1,2×2, 4×4, 2×8, etc) are set in the mold on top of the ceramic fiber paper. A top layer of ceramic fiber paper is next placed on the array of reinforcement preforms and the mold cover seals the mold. The reinforcement porous preform(s) are held to the center of the mold cavity when the sealed mold compresses the top and bottom layers of ceramic fiber paper. The ceramic fiber paper exerts an equal and opposite force on the reinforcement preform(s) within the closed mold centering the preform(s) within the mold cavity. The mold cavity is next infiltrated under pressure with molten metal allowing for metal to penetrate into any open porosity of the ceramic fiber paper, reinforcement preform(s), and areas within the mold cavity that contain open spaces. Subsequent to molten metal infiltration, the aluminum rich surface layers are equal thickness on both sides of the reinforcement preform(s).
    • 公开了一种制备具有均匀表面层的金属基复合材料(MMC)的方法。 首先,将低体积分数的可压缩的不连续的陶瓷纤维纸设置在模腔的底部。 接下来,在陶瓷纤维纸的顶部的模具中设置加强预成型体(1×1,2×2,4×4,2×8等)的排列。 陶瓷纤维纸的顶层接下来放置在加强预成型件的阵列上,并且模具盖密封模具。 当密封模具压缩陶瓷纤维纸的顶层和底层时,加强多孔预成型件被保持在模腔的中心。 陶瓷纤维纸在封闭模具内的加强预成型件上施加相等且相反的力,使预成型件在模腔内定心。 模具腔随后在压力下渗入熔融金属,允许金属渗透到陶瓷纤维纸,加强预成型件以及模具腔中包含敞开空间的区域中的任何开孔。 在熔融金属浸渗之后,富铝表面层在加强预成型件的两侧具有相等的厚度。
