Abstract
The recovery of flow stress and electrical resistivity in shock-deformed iron manganese alloys has been investigated. It was found that the initial stage of recovery is associated with migration of vacancies, while in the last stages of recovery, dislocation climb appears to be important. Three stages of recovery, III, IV and V, have been identified, with activation energies 0·87 eV. 1·39 eV and 2·66 eV. The results sugest that shock deformation generates an appreciably greater number of vacancies than of interstitials.
