The annealing processes of deformation-induced defects after cold-rolling to about 30 and 60% thickness reduction were investigated for Ag-21, 23, 28 at% Zn by means of residual electrical resistivity, microhardness, light microscopy and transmission electron microscopy (TEM). Three annealing stages have been detected and consistently interpreted as annealing-out of mainly point defects and their agglomerates (state 1), formation of dislocation cells and recrystallized strain-free grains (stage 2) and grain growth (stage 3). Further, it is tried to determine the evolution of defect production (point defects and dislocations) during rolling deformation from measured changes of electrical resistivity and microhardness.
