摘　　要：通过SEM-EBSD分析研究了在再结晶初期强磁场退火对冷轧IF钢板再结晶织构的影响.将样品加热到650℃分别保温0,10,30 min以获得部分再结晶的样品.磁场退火时磁场方向平行于样品的横轧向,所施加的磁场强度为12 T.结果表明,在再结晶初期,与其他{111}取向的再结晶晶粒相比,磁场退火有利于{111}〈112〉取向的再结晶晶粒首先形核和长大.The effects of high magnetic field annealing on the recrystallization texture in the initial stage of recrystallization in as-annealed interstitial-free（IF） steel sheet were investigated by the SEM-EBSD analysis.The annealing was conducted in a 12-tesla magnetic field at 650 ℃ which was held for 0,10 and 30 min separately to obtain the partially recrystallized microstructure in samples.It was found that the {111}〈112〉 texture component,as compared with other {111}texture components,was favored by the applied high magnetic field in the initial stage of nucleation and growth.
