After wire-drawing, the orienlation dependent stored elastic energy was measured by neutron diffraction in electroiylic tough pitch copper (ETP 99.99'^ Cu) wires to improve the knowledge on the chemical composition effeci on the static recrystallization behavior The line broadening measurements on relatively low deformed samples have shown thai the stored energy related lo the main libers-the texture develops major (111 \(iww) and minor (001 \{uvw} fibers-is about 2-4 J/mol and that the stored energy ratio 1111 |(MfM')/{001 \{iivw) decreases when the total impurity content increases. Some hypotheses about the relationship between recrystallization process, recovery and stored energy are finally proposed, and some assumptions about the recrystallization mechanisms are set.
