This work presents microstructural analysis of medium carbon steels, based on automated serial sectioning using optical microscopy. The microstructural phases considered here are ferrite, martensite, and pearlite. Typically conventional 2D microscopy is used to analyze these phases, with eddy current or ultrasonic methods as alternatives. Medium carbon steel samples were heat treated and either slowly cooled in the furnace, or quenched. This resulted in differing microstructures in the samples. The analysis was conducted with Robo-Met.3D, a fully automated serial sectioning system that generates two-dimensional optical microstructural data for three dimensional reconstructions. Based on optical microscopy, volume cubes of hundreds of microns on edge were imaged and reconstructed to conduct phase volume analysis. The system proved capable of collecting image data with high fidelity, and controlled slice thickness in an automated manner. The resultant dataset was useful in visualization and analysis of pearlite, martensite, and ferrite phases in steel samples.
