Abstract

The discovery of high temperature superconducting (HTS) Y-Ba-Cu-O ceramics, with a transition temperature above that of liquid nitrogen1, issued the challenge to produce Y-Ba-Cu-O based conductors for practical usage. One of the first methods developed to produce the brittle intermetallic compound-based superconductors, was to deform the Y-Ba-Cu-O powder in a ductile can2. This method was employed to produce wire specimens based on A15 compounds (Nb3Sn)2, NaCl-(NbN)3,4, and Chevrelphases (PbMo6S8)5. The deformation stability problem of such conductors is not related to the crystallographic structure or the superconducting properties of an enclosed powder but is rather determined by factors such as powder dispersivity, mechanical properties of the canning material and the ratio between the canning and the powder-core areas4,6.
