The kinetics of short-range ordering were investigated by means of residual resistometry measurements during isochronal and isothermal heat treatment after cold-rolling to thickness reductions of between 30 and 60%. The resistivity changes which were due to pure ordering could be separated from the measured total resistivity change, which included defect annealing effects. It was observed that quenched-in surplus vacancies contributed appreciably to the ordering process in the recrystallized state. It was concluded that short-range ordering kinetics under equilibrium vacancy conditions could be better observed in the post-deformation annealed condition. In this state, deformation-induced point defects were annealed-out, but a relatively high dislocation density remained to act as a vacancy sink.
