Real-Time Investigation of Recovery, Recrystallization and Austenite Transformation during Annealing of a Cold-Rolled Steel Using High Energy X-ray Diffraction (HEXRD)
Abstract
The annealing process of cold-rolled ferrite/pearlite steel involves numerous metallurgicalmechanisms as recovery/recrystallization of deformed phases, ripening of carbide microstructure,and austenite transformation in the intercritical domain. The interactions between these mechanismsgovern the morphogenesis of the transformed austenite microstructure and, thus, the final propertiesof the steel. This paper demonstrates that high energy X-ray diffraction (HEXRD) on synchrotronbeamline offers the unique possibility to follow concomitantly these mechanisms in situ duringa single experiment. A cold-rolled ferrite-pearlite steel dedicated to the industrial production ofDual-Phase steel serves as case-study. Synchrotron experiments have been conducted in transmissionat 100 keV with a 2D detector. Diffraction patterns acquired all along an annealing treatment are firstanalyzed after circular integration. A Rietveld refinement procedure coupled with a Williamson-Hallapproach is used to determine phase transformation and recovery kinetics. In this paper, a newmethod inspired by the 3D X-ray diffraction tomography is proposed to follow recrystallizationkinetics at the same time. It is based on a systematic detection of individual diffraction spots relatedto newly recrystallized grains appearing on Debye-Scherrer rings. The deduced recrystallizationkinetics is compared and validated by more conventional ex situ methods.
