Study of Texture and Grain Boundary Character Distributions of IFSteels
IF钢织构与晶界特征分布的研究

The batch annealing and continuous annealing of IF steel sheets have been simulated. Texture, grain boundary character distributions (GBCD) and their relations with secondary working embrittlement (SWE) were investigated by electron back-scatter diffraction (EBSD).The results show that the two kinds of IF sheets are great difference in texture and grain boundary character distributions: (1) Continuous annealing IF sheets have a strong 111 recrystallization texture composed , while the batch annealing IF sheets is composed of weak texture ; (2) Large numberCSL boundaries produced in continuous annealing IF sheets, while in batch annealing IF sheets CSL boundaries obviously occurred; (3) Low energy boundaries distributed uniformly in continuous annealing IF sheets, while in batch annealing IF sheets low energy boundaries are accumulative, and random boundaries distribute around the low energy boundaries to form a thick network, which leads to the SWE.
