Analysis of microscopy techniques to measure segregation in continuous‐cast steel slabs

The accurate characterisation of centreline segregation requires precise measurements of composition variations over large length scales (10 ${}^{-1}$ $m$ ) across the centreline of the cast product, while having high resolution, sufficient to quantify the significant composition variations between dendrites due to microsegregation at very small length scales (10 ${}^{-5}m$ ). This study investigates the potential of a novel microscopy technique, named …
