Manufacturing process to reduce large grain growth in zirconium alloys
Patent
·
OSTI ID:6718954
A method is described of treating cold worked zirconium alloys to reduce large grain growth during thermal treatment above its recrystallization temperature. The method comprises heating the zirconium alloy at a temperature of about 1300/sup 0/F. to 1350/sup 0/F. for about 1 to 3 hours subsequent to cold working the zirconium alloy and prior to the thermal treatment at a temperature of between 1450/sup 0/-1550/sup 0/F., the thermal treatment temperature being above the recrystallization temperature.
