Void nucleation is the main damage evolution mechanism involved in the mechanical failure of first-generation Advanced High Strength Steels (AHSS) of the Complex-Phase (CP) class. In lower-strength CP steels, µ-tomography can be used to evaluate damage evolution due to their large grain size. However, in higher-strength grades, the finer grain structure renders µ-tomography unfeasible due to its resolution. Since the distribution of microconstituents, particularly of interfaces with high hardness contrast, is the main contributing factor to void nucleation, an alternative characterization approach involves determining the distribution of interphase boundaries. In the present work, Electron Backscatter Diffraction (EBSD) maps were segmented using image processing techniques to better understand the interphase boundary distribution in CP steels produced on an industrial scale. |
