Critical Condition for Dynamic Recrystallization for High Carbon Steels

A softening mechanism for dynamic recrystallisation has been determined through analysis of the continuous compression flow curves of both hypoeutectoid and hypereutectoid steels, 0\ub77 and 0\ub79% carbon respectively, in the range 900 \u2013 1050\ub0C for strain rates 0\ub701 to 1 s 121. 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.NRC publication: Ye
