Effect of strain on stored energy and recrystallization of straight-rolled silver

Abstract

Stored energy measurements were taken using a heat flux differential calorimeter, and the recrystallization kinetics were established for high purity and commercial silver straight rolled between 55% and 95%. The stored energy of deformation was found to increase almost linearly with the strain except for two well defined degrees of rolling. These “critical” strains exhibit a decrease in stored energy and an acceleration of recrystallization. There is some evidence that increasing the degree of deformation can lead to structure transitions which accelerate the recrystallization. This acceleration was identified as being a result of stimulated nucleation arising from the shear bands.
