Abstract: An experimental setup was designed to study the recrystallization kinetics of Interstitial Free (IF) steel in this work. The 80% cold rolled IF steel foils are heated rapidly to 680°C, 730°C and 780°C by a salt bath. The recrystallization kinetic curves were obtained by the quantitative analysis of texture components, microstructures and EBSP (electron back-scattering patterns) measurements. With the help of EBSD, the orientations of the recrystallization nuclei are determined. The growth rule of the recrystallization nuclei was analyzed statistically. The effect of nucleus orientation on the formation of the recrystallization texture was investigated.

Abstract: Dissociated domain boundaries (DBs) attached to meta-dislocations have been found in a structurally complicated alloy phase (SCAP) of ξ'-Al-Pd-Mn. On the basis of HREM observations and theoretical simulation, a structure model of DBs is proposed. The displacement vector R for the DB is determined to be 1/2 [1, 0, 1/τ] with a length of 12.37 Å.
