Abstract

Annealing studies of cold-rolled Ni3Al established that the recrystallization kinetics obey the Avrami equation and that the grain-growth kinetics obey the relation ¯d=Ctn where ¯d is the average grain size, t the time and C and n are parameters whose magnitude depends on temperature. Disorder is introduced during deformation but subsequently removed during recrystallization. Antiphase boundaries are found in some recrystallized grains but do not show any preference to lie on {100} planes, contrary to predictions based on Flinn's nearest-neighbour approximation model. Twins, dislocation networks an planar faults are also found in recrystallized grains.
