Microstuctural changes after warm rolling of an interstitial free steel have been studied by annealing deformed specimens in a salt bath in the ferrite temperature range. Static recovery and recrystallisation were followed by Knoop hardness measurements, optical microscopy, and TEM. The results show that the kinetics of the static restoration processes are systematically dependent on deformation variables. However, occurrence of some precipitation during static restoration affects the kinetics of the process and the extent to which they proceed.
