Abstract: 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.

Abstract: The apparatus and method for spray casting a spray of molten metal on a moving substrate. The leading edge of the spray pattern is deflected away from or into the spray pattern to eliminate the cooler and less dense particles of the leading edge from contacting the substrate. The deflector preferably has a surface of non-wetting material to prevent the build up of material thereon.

Abstract: Spray cast alloys having reduced porosity and increased ductility are provided as well as a process for the manufacture of the alloys. An effective amount of a reactive metal which reacts with the spray casting atmosphere but not with the desired alloy is dissolved into the alloy prior to spray casting. Preferred reactive metals readily form a nitride which is finely dispersed throughout the spray cast alloy.

Abstract: 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.

Abstract: A predominately beta phase copper base alloy which is adapted for forming in a semi-solid slurry condition. The alloy has a microstructure comprising discrete particles within a lower melting point matrix and consists essentially of from about 9% to about 10.5% by weight aluminum, at least about 10% by weight nickel and the balance essentially copper. In accordance with an alternative embodiment the nickel can be replaced on a one for one basis by iron within certain limits. The alloys are processed by chill casting with a cooling rate throughout the section of the casting comprising at least about 10.degree. C./sec. The alloys as-cast or when reheated to a semi-solid exhibit a microstructure suitable for press forging.

Abstract: A method and apparatus for the casting of metals in which a molten stream of metal is atomized into a spray of highly liquid droplets. The droplets are deposited on a moving substrate such as an endless belt provided with side dams. The droplets flow in a direction transverse to the direction of movement of the substrate and are contained by the side dams. The droplets may have an average size of 300 microns and the spray may have a liquid to solid ratio of at least 50%. This arrangement overcomes the problems of splashing and turbulence caused by the relative flow between the melt and the belt in regular belt casting and overcomes porosity problems associated with spray casting.

Abstract: A method for the manufacture of a copper based alloy and the alloy produced thereby having improved mechanical properties. An alloy containing a dispersoid ingredient and a precipitating ingredient are spray cast so that during spray casting the dispersoid ingredient forms a second phase as a uniform dispersion of relatively small dispersoids. After solution treating and aging, the solid state precipitating ingredient precipitates as a third phase of a solid state precipitate.
