Abstract

Abstract

The recrystal course is observed through annealing temperature of 800℃ and variation annealing time in extra-deep drawing IF steel. It is processed in soak temperature of 1 200℃, finish temperature of 930℃, coiling temperature of 700℃ and cold reduction of 80%. According to experamental result, the recrystallization nucleation principle in preliminary annealing is discovered in IF steel of micro-carbon, micro-titanium and micro-niobium. The principle is that the recovering, poly-gonization begins at the subgrains of {111} orientation, then these subgrains grow up prevailing. The texture mainly consisting of {111} orientation is formed.
