The in-situ study on the micro-structural characters of IF steel at early stage of recrystallization using high-energy X-ray

摘要：

High-energy synchrotron diffraction offers great potential for experimental study of recrystallization kinetics. A fine experimental design to study the recrystallization mechanism of Interstitial Free (IF) steel was implemented in this work. In-situ annealing process of cold-rolled IF steel with 80％ reduction was observed using high-energy X-ray diffraction. Results show that, the diffraction intensity of 001<110> and 112<110> belong to α-fiber texture component decreased with the annealing temperature increased while 111<110> did nearly not change and 111<112> increased; the FMTH decreasing and d-space changing with annealing temperature increasing indicated that the residual stress relaxed completely during recovery.
