| Spanish abstract | Resultados de pruebas de tensi´on en cables superconductores a temperatura ambiente y a temperatura de nitr´ogeno l´ıquido son mostrados. Las mediciones de deformaci´on al comienzo de la prueba est´an propensas a error debido a la flexibilidad propia del cable y a su curvatura. Esto causa un error de traslaci´on en los gr´aficos que se corrige al utilizar el m´odulo de elasticidad proveniente de las pruebas. La informaci´on obtenida en las pruebas de varios espec´ımenes provenientes del mismo material mostr´o visibles irregularidades a priori pero despu´es de ser analizadas con t´ecnicas de an´alisis estad´ıstico significantes resultados pudieron ser revelados |
| English abstract | The results of tensile tests on superconducting wires at room and liquid nitrogen temperatures are presented, and the apparatus and method used to obtain these results are described. The strain measurement at the start of the tests is prone to error due to wire flexibility and specimen curvature. This causes a translation error on the graphs that is approximately corrected for by utilising knowledge of the Young’s modulus determined from the test. The data from the tests of numerous specimens of the same wire can show significant scatter, but meaningful results are obtained by using statistical analysis techniques |
