Traditional metallographic preparation of cast iron provides little information about the solidification of the material. Coloretching with Motz reagent reveals the microsegregation patterns of Silicon in the material, which provide a detailed account of the material’s solidification procedure and structure. This Webinar provides practical guidelines on how to apply the color etching method, details about its mechanism, and useful examples of what it can tell us about Cast Iron. After the lectures, the audience is invited to discussions about the color etching technique and its potential applications for industry and research.
