Cold Rolling - an overview | ScienceDirect Topics

Cold rolling reduction is an important factor that affects drawability of IF steel It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34]This effect has been shown in Fig 514Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35]...
