Abstract
The recrystallization temperature at definite time and recrystallization holding time at constant temperature for two IF high strength steels were measured by annealing in salt bath.Based on measurement result of heat-up time in salt bath ,according to the formula arrhenius the recrystallization activation energy of the two steels was calculated,and the recrystallization temperature under the holding time for 30 s,60 s,90 s was defined.
