Abstract
A method for fabricating silver or silver alloy tube stock. The method provides silver or silver alloy tube stock with a structure that is substantially free of defects, has a fine grain size, and is amenable to uniform deformation. The silver or silver alloy tube stock is used to make silver-superconductor monofilament or multifilament precursor articles and composites.
