摘　　要：本文选用了超深冲IF钢,经1200℃开轧、930℃终轧、700℃卷取和80％冷轧后,在800℃不同时间退火并观察其再结晶过程。实验结果表明.微碳、钛、铌IF钢在退火初期,{111}平行于板面亚晶首先发生回复、多边化,而后形成再结晶晶核,同时这种取向的晶粒优先长大从而形成{111}纤维的织构,其它取向的品粒较迟发生回复或被生长着的{111}平行于板面取向的晶粒吞并。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.
