Abstract

Procédé pour réduire les contraintes internes dans un supraconducteur dont le composé supraconducteur est formé de deux constituants par traitement thermique d'un produit intermédiaire correspondant. Pour la formation du produit intermédiaire 6, on incorpore le premier constituant 4 dans une matrice 7 normalement conductrice, dont la section transversale est au maximum le double de celle du premier constituant 4, et on fait diffuser au moins une partie du second constituant 8, lors du traitement thermique, de l'extérieur dans le produit intermédiaire 6. Application : notamment à la fabrication de supraconducteurs pour des électro-aimants supraconducteurs.Process for reducing internal stresses in a superconductor in which the superconducting compound is formed from two constituents by heat treatment of a corresponding intermediate product. For the formation of the intermediate product 6, the first component 4 is incorporated into a normally conductive matrix 7, the cross section of which is at most twice that of the first component 4, and at least part of the second component 8 is diffused, during heat treatment, from the outside in the intermediate product 6. Application: in particular to the manufacture of superconductors for superconducting electromagnets.
