To understand complex micro-mechanical phenomena in multi-phase alloys, we have recently developed an experimental-numerical methodology. This approach consists of in-situ scanning electron microscopy deformation experiments assisted by electron backscatter diffraction (EBSD) and microscopic-digital image correlation (μDIC) analyses, focused ion beam milling assisted internal stress measurements and crystal plasticity simulations. As a result of the optimization of the specimen surface conditions, DIC pattern particle characteristics and electron beam imaging conditions, the method enables selective imaging of particles or the microstructure, an essential ingredient for high quality mapping. Here we present the application of the method to unravel the underlying micro-mechanical processes responsible of the continuous yielding phenomena in DP steel.
