ABSTRACT:
A process for the production of superconductor wires or cables of Nb.sub.3 Al which consists in superimposing sheets of Nb to sheets of Al, inserting the superimposed sheets in a copper container, subjecting the copper container with the sheets contained therein to a plastic deformation processing so as to obtain a reduction in the thickness of the Al sheet to a value of less than about 1.5.mu.m and finally subjecting this product to heat treatment at a temperature between 800.degree. and 1000.degree. C.
