Abstract: A PROCESS FOR PRODUCING A ZIRCONIUM BASE ALLOY MEMBER HAVING IMPROVED TENSILE STRENGTH AND DUCTILITY PROPERTIES PRIOR TO NUCLEAR RADIATION BY FIRST COLD WORKING THE MEMBER TO INDUCE A 7% TO 20% STRAIN. THE MEMBER IS THEN HEAT TREATED AT TEMPERATURES LOWER THAN THE USUAL ANNEALING TEMPERATURES.
