The annealing phenomena and thermal stability of severely deformed steel sheet

► Increasing of mechanical properties of CGPed sheets with annealing up to 400 °C. ► Acceptable thermal stability by annealing up to 400 °C. ► Lowest inhomogeneity factor of CGPed and annealed sheets at 400 °C. ► Abnormal grain growth of CGPed sheets by annealing at temperatures above 400 °C.
