🚨New paper: "Improving parent-austenite twinned grain reconstruction using electron backscatter diffraction in low carbon austenite" by @drruthb.bsky.social @bmatb.expmicromech.com and Warren Poole in Scripta Materialia (2025) - we use #EBSD and improve the analysis of steel doi.org/10.1016/j.sc...

A graphical abstract that shows how we go from an initial microstructure map and apply a reconstruction algorithm, which we improve using a 'resort' procedure. The new algorithm has a better looking and more realistic microstructure.
