Abstract
Plane strain compression tests have been carried out on Ti stabilised interstitial free steel
at 700oC with constant and changing strain rates. Specimens were annealed in a salt bath at 750oC
to determine the effects of changing strain rate on the kinetics of static recrystallisation and on the
recrystallised grain size. After relatively slow changes in rate, the recrystallisation behaviour at the
end of the change was the same as for tests at constant strain rate with the final value. For faster
changes in rate, there were transients in recrystallisation rate and recrystallised grain size at the end
of the change in strain rate at a strain of 1.0. These were removed by a further increment of 0.1
strain at constant rate. In all cases the recrystallised grain size correlated with the subgrain size
present at the end of deformation.
