摘要： A high ductility, high strength, moderate conductivity aluminum conductor article and process for making the article are described. The article is a conductor of elongated geometry containing a low volume fraction of intermetallic fibers which are aligned parallel with the major axis of the conductor. The surrounding matrix is aluminum of at least commercial purity to which from 0.5 to 1.5% copper has been added. The fabrication process involves the coupled solidification of eutectic and slightly proeutectic compositions to produce a fibrous microstructure, followed by mechanical working. The ductility of the finished article will exceed about 5%. The final properties may be varied by heat treatments. The broad composition is 1.0-2.0% Co, 0.5-1.5% Cu, balance aluminum.

摘要： Photon absorbing surfaces which are effective over a broad band of photon energies are described. These surfaces consist of a two-phase material with a protruding second phase whose dimensions are on the order of microns. Photons are absorbed by multiple reflections within the region of the protruding phase. The surfaces are produced by directional solidification of eutectic compositions to produce aligned second phase microstructures within a metallic matrix. The matrix material is then selectively removed to expose the second phase material.

摘要： Supported fibrous skeletal metal catalysts and methods of producing such catalysts are described. The catalysts are produced by directionally solidifying a eutectic composition to produce a microstructure consisting of oriented intermetallic single crystal fibers in a metallic matrix. Selective means are employed to remove a portion of the matrix to expose a portion of the fibers. Leaching means are employed to preferentially remove one of the atomic species from the exposed intermetallic fiber. The exposed leached fibers are porous, have a high surface area and display catalytic activity, depending upon the starting eutectic composition.
