Abstract

Attempts have been made to improve high field properties of continuous ultrafine Nb3Al multifilamentary superconductors. The Al core, of which the hardness is a key to the excellent cold-workability of the Nb/Al composite, was hardened by being alloyed with Ge by the combination with Cu and Ag, resulting into an increase in Tc, Hc2 and Jc of the Nb/Al composite at high fields. Very short heat treatments at temperatures above 1200°C were carried out by applying a large current pulse directly to the sample so that remarkable improvements in high field properties are attained.
