| 摘 要： | 对IF钢板的罩式退火工艺和连续退火工艺进行了模拟，并运用电子背散射衍射(EBSD)技术研究了两种退火工艺处理的IF钢板的再结晶晶粒尺寸、显微织构和晶界特征分布及其与二次加工脆性间的关系。试验结果表明，两种退火工艺的IF钢板在再结晶晶粒尺寸、显微织构和晶界特征分布上存在很大的差异，这种差异导致了两种退火工艺的实验钢板在深冲性能和韧脆转变温度上的差异。

| Abstract: | The batch annealing (BA) and continuous annealing (CA) of IF steel sheets have been simulated, and recrystal grain size, microtexture, grain boundary character distributions (GBCD) and which related with secondary working embrritlement (SWE) were investigated by electron back-scatter diffraction (EBSD). The results show that the two kinds of IF sheets are great difference in recrystal grain size, microtexture and grain boundary character distributions and which lead to the difference in formability properties and ductile-brittle transition temperature (DBTT) between two kinds of annealing technology of sheets. |
