This work presents a three dimensional microstructural analysis of medium carbon steels, based on serial sectioning using optical microscopy. The microstructural phases considered here are ferrite and pearlite.
Medium carbon steel samples were heat treated in a furnace and either slowly cooled in the furnace, or cooled at higher rates. This resulted in different pearlitic microstructures in the samples. The analysis was conducted with Robo-Met.3D®, a fully automated metallography system for serial sectioning. Based on optical microscopy, combined with etching, volume cubes of hundreds of microns on edge were imaged and reconstructed to conduct grain size and phase volume analysis.
