Abstract Scope |
As global warming accelerates, aluminium alloy with high specific strength has drawn attention for weight reduction of car bodies. However, the formability of aluminium is generally inferior to that of steel sheets. It is well known that the formability of the metal sheets with a FCC structure can be greatly improved by the presence of the <111>//ND textures. Asymmetric rolling is a process which improves the formability of aluminium sheets by introducing an intense shear deformation and the <111>//ND textures. Because 6061 aluminium alloy is a precipitation-hardening alloy, containing magnesium and silicon as its major alloying elements, it is necessary to identify the effects of precipitates on shear deformation and texture control. In this research, the effect of initial precipitates on shear deformation in 6061 aluminium alloy was studied. The formability by initial precipitates was evaluated and the texture of the rolled aluminium alloy sheets was analyzed. |
