A softening mechanism for dynamic recrystallisation has been determined through analysis of the continuous compression flow curves of both hypoeutectoid and hypereutectoid steels, 0·7 and 0·9% carbon respectively, in the range 900 – 1050°C for strain rates 0·01 to 1 s−1. The critical stress and strain for the initiation of dynamic recrystallisation were determined from the inflection points in plots of strain hardening rate against flow stress.
