At temperatures above 950 deg F, zirconium which was strained a critical amount will experience critical recrystallization. The large grain size thus formed can result in a reduction in the fatigue life by a factor of 2 to 9 at both high and low temperatures. The critical strains for zirconium vary from 15% at 900 deg F to about 2% at 1125 deg F, while those for Zircaloy III vary from 15% at 1050 deg F to 5% at 1200 deg F. Zircaloy II experiences no critical recrystallization up to 1200 deg F. (auth)
