Abstract Scope |
A new class of aluminium alloys show enhanced mechanical properties, which has been partially attributed to a careful design of chemical composition and process. Recent work on an extruded high strength 6xxx Al alloy has shown that the mechanical properties may be influenced by its crystallographic texture. This contribution presents detailed studies of the effect of profile shape on resultant microstructure, micro-texture and tensile properties of Al 6xxx alloy.
All extruded samples exhibit a fibrous microstructure. However, the average grain size increased rapidly from thin to bulk geometries. In addition, the texture changed from similar to rolling for thin profiles to that typical of extrusion for bulk.
Finally, the same aluminium alloy exhibits a mechanical property profile that depends on its shape, which can be correlated with differences in crystallographic texture. This clearly shows that the strength could be engineered through the control of microstructure and crystallographic texture during extrusion. |
