In modern multiphase materials, damage initiation and growth usually occur during forming and service. The key to understand the initiation and growth of voids in such materials is the characterization of the microstructural mechanisms in a statistically relevant manner over a large number of damage sites. Here, we propose to use DCT scans to determine the shape, arrangement, orientation and grain average elastic strain tensor of a representative ensemble of grains (4000-9000 grains) during mechanical loading of samples of age-hardened Al6010 multiphase alloys. Based on grain shape and orientation as well as the strain and stress distribution, plastic strain localizations can be detected and the specific morphological and crystallographic boundary conditions for the strain localization and subsequent damage initiation can be analysed in detail The “single grain” behaviour and specific nearest neighbour correlations will be used as input parameters for CP-FEM modelling.
