Abstract
The effects of rolling temperature on the microstructure, mechanical anisotropy, and formability of 7B52 laminated aluminum alloy were studied using uniaxial tensile testing, Erichsen cupping test, scanning electron microscopy, and backscattered electron diffraction. The results indicate that 7B52 sheets are all well-bonded when rolled at 370°C, 420°C, and 470°C. The comprehensive mechanical properties of the sheet continuously improved as the rolling temperature decreased. When the rolling temperature decreased to 370°C, the as-quenched sample exhibited the lowest anisotropy and the optimum formability, with an in-plane anisotropy (IPA) value of 3.0 and an Erichsen index (IE) value of 6.9 mm. The excellent mechanical properties of the sheet are mainly due to the finer grains, lower grain aspect ratio, higher recrystallization volume fraction, and the balance of Goss and S texture components.
