This report describes work on producing dispersion strengthened copper alloys using melting and casting techniques as opposed to more conventionally used powder metallurgy techniques. Two methods of approach are described. One method produces copper-thorium boride alloys by liquid phase precipitation. Cu-2% ThB4 alloys produced by this technique show 10 to 80% improved tensile properties, two-to-three orders of magnitude improved creep and stress-rupture properties together with a 2 to 10% increase in electrical resistivity. The second method produces a copper-aluminum oxide alloy by a solid state diffusion reaction following melting and casting. The precipitate formed is extremely fine, resisting recrystallization at 1000C for 24 hours. (Author).
