Superconductivity - Part 19: Mechanical properties measurement - Room temperature tensile test of reacted Nb3Sn composite superconductors
IEC 61788-19:2013 covers a test method detailing the tensile test procedures to be carried out on reacted Cu/Nb3Sn composite superconducting wires at room temperature. The object of this test is to measure the modulus of elasticity and to determine the proof strength of the composite due to yielding of the copper and the copper tin components from the stress versus strain curve. Furthermore, the elastic limit, the tensile strength, and the elongation after fracture can be determined by means of the present method, but they are treated as optional quantities because the measured quantities of the elastic limit and the elongation after fracture have been reported to be subject to significant uncertainties according to the international round robin test. The sample covered by this test procedure should have a bare round or rectangular cross-section with an area between 0,15 mm2 and 2,0 mm2 and a copper to non-copper volume ratio of 0,2 to 1,5 and should have no insulation. Key words: supraconductivity, mechanical properties

Supraconductivité - Partie 19: Mesure des propriétés mécaniques - Essai de traction à température ambiante des supraconducteurs composites de Nb3Sn mis en réaction
La IEC 61788-19:2013 spécifie une méthode d'essai détaillant les modes opératoires d'essai de traction à exécuter à température ambiante sur des fils composites supraconducteurs de Cu/Nb3Sn mis en réaction. L'objectif de cet essai est de mesurer le module d'élasticité et de déterminer la charge d'épreuve du composite due à la déformation du cuivre et des composants en cuivre et en étain sur la courbe de contrainte en fonction de la déformation. De plus, la limite élastique, la résistance à la traction et l'allongement après fracture peuvent être déterminés par le biais de la présente méthode, mais ils sont traités comme des grandeurs facultatives, car l'essai interlaboratoire international a démontré de considérables incertitudes au sujet des valeurs mesurées pour la limite élastique et pour l'allongement après fracture. Il convient que l'échantillon couvert par la présente procédure d'essai ait une section transversale circulaire ou rectangulaire avec une surface comprise entre 0,15 mm2 et 2,0 mm2 et un rapport volumique entre le cuivre et le non-cuivre de 0,2 à 1,5. Il convient également qu'il n'ait pas d'isolation. Mots clé: supraconductivité, propriétés mécaniques
