The paper compares model predictions of recovery kinetics of low carbon steels
with activation parameters determined by various experimental techniques. It is concluded
that the stress relaxation method overestimates the recovery rate because the creep of stressed
specimens is ignored. To avoid such errors, it is recommended to use an alternative method of
double loading. The more realistic (lesser) rate of recovery with the related activation
parameters complies with independent data of mechanical tests.
