The break-up of complex shaped inter-metallic iron-rich particles (∼26 000 mm−3) in an aluminum alloy during industrial hot rolling was analyzed. A new segmentation algorithm with multiclass thresholding was developed. The particle break-up was analyzed stastically and by a mechanical FEA-based model. The present work proves the feasibility of a particle classification with a subsequent finite element-based mechanical modeling.
