ժҪ High-energy synchrotron diffraction offers great potential for experimental study of recrystallization kinetics. An experimental design to study the recrystallization mechanism of interstitial-free (IF) steel was implemented. The whole annealing process of cold-rolled IF steel with 80% reduction was observed in situ using high-energy X-ray diffraction (HEXRD). The results show how the main texture component of IF steel change, i. e. the �� ��<110>��rolling direction (RD)�� fiber texture decreases and the �� ��<111>��normal direction (ND)�� fiber texture increases. The important part of the �� fiber texture is that both the {100}<011> and {112}<011> texture decrease at the beginning of recrystallization. The �� fiber texture increases at the early stage of recrystallization which stems from the increase of {111}<112>. Nevertheless, the {111}<110> does not change after recrystallization. The dynamic evolution of the main texture components {100}<011>, {112}<011>, {111}<112> and {111}<110> is given by in-situ HEXRD.
