Effect of strain rate on forming process

Effect of strain rate on forming process

Higher the rate of strain hardening, lower is the recrystallization temperature. For mild steel, recrystallization temperature range may be taken as 550–650°C. Recrystallization temperature of low melting point metals like lead, zinc and tin, may be taken as room temperature. The effects of strain hardening can be removed by annealing above the recrystallization temperature.
