Prediction of Earing of Hot-Rolled Al Sheets from Pole Figures

The formation of uneven cup heights during deep drawing is called earing. This phenomenon caused by the planar anisotropy formability in sheets, which result crystallographic texture. In addition to analytical and finite element methods, a simple quick method was developed recently predict earing profile Al sheets solely from data {200} pole figures. So far, applied on final state cold rolled 0.3–3 mm thickness subsequently annealed. Within this manuscript, prediction 3003 type with ~6 mm, being hot-rolled state. Texture examinations were performed at different depths, profiles calculated. For comparison, calculated Lankford values that determined tensile tests. It shown case if grain structure uniform across sheet, can be appropriately full figure obtained surface X-ray Diffraction (XRD) texture measurements.
