Abstract
A process for incorporating a superconductive compound or compounds by fusion in a base metal having good electrical and heat conductive properties, such as copper, silver, aluminum, and the like. The process involves preparing a melt of the base metal and of the alloy components which combine to form the superconductive compound or compounds having a .beta.-W (A 15) structure. Then the melt is solidified at a cooling rate of at least 1000.degree. C./sec. whereby a ductile superconductive alloy is formed wherein the individual particles of the superconductive compounds are finely distributed in the base metal and are mutually spaced with respect to each other in such a way that the critical value for the tunnel effect is not exceeded.
