摘要： Tubes or other symmetrical shapes are formed of composite materials, such silicon carbide and aluminum, by spin casting. The reinforcing material can be precast into a billet or bar of the matrix metal, remelted and introduced into a spinning mold. Tubes can be produced with walls having differing amounts of reinforcing materials in the tube wall. Castings can be obtained having a uniform distribution of a reinforcement in a matrix metal.

摘要： A Nb-Ti or Nb-Zr low temperature superconducting (LTS) wire is coat with ten AgN0.sub.3 which is then decomposed to form a uniform silver metal (Ag) coating on the LTS wire. A uniform coating of molten Al or Al alloy is formed on the Ag coated LTS wire and then solidified. A bundle of the coated LTS wires is inserted into an Al or Al alloy tube and cold worked to form a multifilamentary LTS cable comprising the Ag coated LTS wires each surrounded by an Al or Al alloy matrix.

摘要： Microscopic fibers are mixed with a metal powder to provide a nonuniform mixture with randomly oriented fibers having metal particles adhered thereto. This mixture is extruded at room temperature at least three times, and is then placed in a die cavity and subjected to a first pressure at room temperature. While adding no additional pressure, the die cavity is heated to bring the mixture to a temperature above the solidus of the metal powder, and the volume of the die cavity is decreased to at least the theoretical volume necessary to receive the mixture if the mixture included no voids. The die cavity is then cooled and the resultant billet ejected therefrom.
