The relevance of dynamic recrystallization in the hot deformation of IF steel at high strain rates

Dynamic recrystallization (DRX) occurs ordinarily during low strain rate, hot deformation of low C or IF steels. Nonetheless, important processes are carried out with these materials at high strain rates, where the relevance of DRX has not been discussed. This paper shows how one can estimate a critical strain rate, above which DRX becomes unimportant in the hot mechanical behavior of IF steels, based on experiments carried out at low and moderately high strain rates.
