Relationship between Tensile Deformation and Crystallographic Orientation of Grains in the Balanced Al-Mg₂ Si Alloys

Abstract:

Heat-treatable 6000-series alloys are currently used by automotive body sheets. It is general to improve mechanical properties of the Al-Mg-Si alloy by giving addition of the element and the thermo-mechanical treatment. The electron backscattered pattern (EBSP) technique has been performed in order to analyse individual crystallographic orientation in these alloys. Hardness of the 30%-rolled alloy was higher than that of the 0%-rolled alloy. The Schmid factor of individual crystal grain was calculated by crystallographic orientation. After adding a little deformation, the crack was observed at the interface between higher SF and lower SF grains. It was thought that this crack introduced a fracture from the surface.
