摘　　要：研究了钛（铌固定）对高强度Ｎｂ＋Ｔｉ－ＩＦ冷轧罩式炉退火钢板性能的影响。结果表明，当Ｔｉ／Ｎ≈１（原子比）时伸长率和ｒｍ值最高，随着钛含量的进一步增加，钢中过剩的钛将和磷形成ＦｅＴｉＰ析出相，延迟了再结晶，使伸长率和ｒｍ值降低。The effect of Ti on the properties of cold rolled batch annealed strip has been studied The results show that the steel with Ti/N≈1 (atomic ratio)is the best among four experimental heats in terms of elongation(EL)and r m With the increase of Ti the excess Ti forms FeTiP with P,which delays the recrystallization and decreases EL and r m
