Abstract

A method (the so called "jelly-roll method") has been developed in past years which allows multifilamentary Nb(3)Al wires to be obtained. A short description of this process as well as a review of the experimental results obtained on short samples are presented and discussed. The main result of this work is that a superconductor with a very high critical current density (1.8 to 1.9 x 1.0 E9 A/m2 at 11T) can be produced which makes this material very interesting for practical purposes. However, problems related to the production of significant lengths of wire remain still open. Possible ways to overcome them are briefly discussed.
