Conclusions 1. Annealed D16T aluminum alloy exhibits anisotropy of its elastic and plastic properties. Alloy plasticity is 45% higher and the Young's modulus 9.5% lower in the rolling direction than in that perpendicular to it. 2. The anisotropy of both elastic and plastic properties decreases as the test temperature is reduced. 3. The deformability of the alloy depends on the type of stress pattern and the temperature. Plasticity increases as the test temperature decreases. At normal and low temperatures, minimum plasticity occurs when the principal-stress ratio σz/σ θ = 0.5. 4. The deformation curves σi = Φ (ɛi) andτ max = f(γmax) are not invariant with respect to the type of stress pattern. A decrease in test temperature to −180° has no material effect on the divergene of the curves.
