Abstract
A tube or rod of zirconium or niobium or their alloys is formed by filling a metal tube with the metal or alloy powder, closing the ends of the tube and swaging the tube at a temperature up to 1000 DEG C. The powder may have a grain size of 0.1-1 mm., the tube may be of stainless steel and for the production of swaged tubes a copper or zinc alloy mandrel is located in the tube, the powder being packed around the mandrel. After cold swaging for zirconium and its alloys swaging is carried out at 500-600 DEG C. and for niobium and its alloys at 700-1000 DEG C. The outer sheath may be removed mechanically or chemically by solution in acid and the mandrel may be removed by melting. The alloying elements used with zirconium may be 1.3-1.6% tin, 0.07-0.7% iron, 0.03-0.16% chromium and 0.03-0.08% nickel.
