| Abstract Scope |
Centerline segregation is an inherent phenomenon in continuous casting, significantly impacting mechanical properties. Although complete elimination is impractical, precise measurement and quantification can enhance final product quality. This study employs VESPERS (VEry Sensitive Elemental and Structural Probe Employing Radiation from a Synchrotron), a novel microscopy technique developed at the Canadian Light Source, to generate large-scale Mn segregation maps from thin-slab-cast steel. Two calibration methods, point analysis and regression analysis, were developed for data quantification. A comparison with traditional imaging techniques including Laser Induced Breakdown Spectroscopy (LIBS), Micro X-ray fluorescence spectroscopy (MXRF), and the Electron Probe Micro Analyzer (EPMA) shows that VESPERS is successful in characterizing centerline segregation. The various imaging techniques yield comparable outcomes in terms of composition maps and solute profiles. The findings also highlight the significance of striking the ideal balance between spatial resolution and field of view to have a thorough understanding of the segregation phenomenon. |
