Abstract The effect of aging on the anisotropic mechanical properties of a commercial 6061 rolling sheet has been investigated by 0°, 45° and 90° uniaxial tensile tests. The mechanical properties of the studied alloy are strongly related to the applied heat treatment state and loading direction, exhibiting visible anisotropy. The T6 treated alloy exhibits the lowest anisotropy as compared with the other treated alloys. In addition,the studied alloys has a strong cube {001} 〈100〉 and a much weaker {001} 〈100〉 components. The artificial aging utilized in present work has little influence on the grain microstructure and texture evolution. The dislocation distributions of T6 and HTA 240 ℃ alloys are denser and more homogeneous as compared with those in other treated alloys, and the visibly higher density of β″ precipitates in T6 alloy is the main reason for the highest strength and the lowest anisotropy.
