<p>The present invention relates to a process for extruding molybdenum-rhenium alloys into tubes or pipes. The invention is capable of high temperature extrusion of MoRe alloys, which comprise about 10 to 50 w.% rhenium, into a seamless pipe or tube. The steps of the process generally comprise fabricating a MoRe billet or blank which includes a pilot hole that extends along the longitudinal axis of the billet (33), heating the billet to a temperature of at least about 1300 °C, and extruding the heated billet by operation of an extrusion press.</p> |
