Abstract

The development and the transition of texture in rolled Al-Mg alloys have been followed by determining pole figures for the alloys with various Mg contents and with various degrees of rolling reduction.

Al-Mg alloys containing 0.5, 1.0 and 2.0 % Mg were prepared by melting in an argon atmosphere and rolled into sheets of 1 mm thickness. The rolling reductions were 70, 82.5, 90 and 95 %. Pole figures were determined with 111, 200 and 220 difractions. The results were analyzed using the orientation distribution function.

For low reduction of rolling, pole figures for all Al-Mg alloys were almost the same as that for pure aluminium, that is, the copper type. For high reduction of rolling, pole figures for the alloys containing up to 1% Mg were the copper type. However, the alloy containing 2 % Mg showed the pole figure of different type. The main component of this texture was represented as {001}<110>.
