【摘要】：借助电子背散射衍射(EBSD)技术与俄歇电子能谱仪(AES)分析了不同温度退火的含磷高强IF钢的再结晶织构、晶界特征与晶界处P、B偏聚量。结果表明:随着退火温度由750℃升高到840℃,IF钢的{111}面织构强度先增加后降低。在810℃退火120 s得到最强的{111}面织构,体积百分含量大约为75%,织构的主要组分是{111}112与{111}110。810℃退火时样品晶界处P、B偏聚量最少,重合位置点阵(CSL)晶界与小角度晶界含量较高。合理控制高强IF钢在再结晶退火温度,有利于降低P晶界偏聚量并获得强度较高的{111}面织构。
[Abstract]:The recrystallization texture, grain boundary characteristics and Pu B segregation at grain boundaries of high strength if steel annealed at different temperatures were analyzed by electron backscattering diffraction (EBSD) and Auger electron spectroscopy (AES). The results show that the {111} plane texture strength of if steel increases first and then decreases with the annealing temperature rising from 750 鈩，
