Abstract
Processes for the rapid alpha annealing of zirconium based articles are described. These processes utilize induction heating to rapidly heat a worked zirconium based article to an elevated temperature after which it is then cooled. Time at the selected elevated temperature is less than about 1 second, and preferably essentially zero. Stress relieving of cold pilgered Zircaloy may be performed by induction heating to a temperature between about 540.degree. and about 650.degree. C. Partial recrystallization annealing of cold pilgered Zircaloy may be performed by induction heating to a temperature between about 650.degree. and about 760.degree. C. Full alpha recrystallization annealing of cold pilgered Zircaloy may be performed by induction heating to a temperature between about 760.degree. and about 900.degree. C.
