摘要： There is disclosed methods for the manufacture of a metal matrix composite having a metal or metal alloy matrix and a uniform dispersion of a second phase. The second phase is either a refractory metal or a nonmetal. An element which reacts with both the matrix and the second phase is added to increase the loathing density of the second phase and to improve adhesion between the components of the composite. When the metal alloy matrix is copper or a copper based alloy, suitable reactive elements include zirconium, titanium, chromium and mixtures thereof.

摘要： A method of making a composite material in which a porous preform is produced by spray casting. An appropriate metal or alloy is caused to infiltrate the interconnected pores. This may be accomplished by infiltrating the porous preform with a liquid metal of a melting point lower than the melting point of the porous preform and thereafter solidifying the infiltrated material or the material can be infiltrated by the use of a slurry containing the desired particles and the liquid carrier driven off by baking the infiltrated preform. Alternatively, infiltration may be accomplished by plating of a desired metal or alloy from an appropriate infiltrate electroplating or electro-less plating solution.

摘要： A method and apparatus for casting an ingot with refined grain structure from a metallic melt supplied to a casting mold. The mold is intermittently cooled to form a zone of fine dendrites on the inner peripheral surface of the mold. Then, the fine dendrites are reheated to detach secondary dendritic arms therefrom. Finally, the detached secondary dendrite arms are mixed into the melt to serve as nuclei for grain refinement as the melt solidifies into a cast ingot having a refined grain structure.

摘要： Spray cast copper-manganese-zirconium alloys are disclosed. In one embodiment, the alloy is spray cast in nitrogen and contains from about 1 ppm to about 20 ppm of dissolved nitrogen. In a second embodiment, the alloy contains an addition selected from the group consisting of chromium, titanium, erbium and mixtures thereof. The alloys are useful for sound damping as the combination of zirconium and the addition inhibits degradation of the specific damping capacity of the alloy.

摘要： There is provided an apparatus and method for the manufacture of metallic articles. A molten metal stream is disrupted, such as by gas atomization, to form a plurality of molten metal droplets. The molten metal droplets pass through a cooling zone having a length sufficient to allow up to about 30 volume percent of each of the droplets to solidify. A mold then receives and completes solidification of the metal droplets. When under about 30 volume percent of the droplets is solid, the droplets retain liquid characteristics and readily flow within the mold.
