On the Study of the Sheet Bendability in AA5754-O Temper Alloy

The bendability of AA5754 aluminum alloy in fully recrystallized temper (O temper) has been studied. Both experimental and numerical work showed that a strong {001}〈100〉 Cube crystallographic texture in the sheet provides improved bendability compared with a low Cube texture sheet, even though the tensile properties of both sheets are similar. A crystal-based finite element model also showed that the textural distribution influences bendability, while the initial surface topography has little effect.
