Influence of magnesium on the rolling texture of polycrystalline aluminum

The effects of the magnesium content, the rolling temperature and the rolling reduction on polycrystalline aluminum were studied. When the rolling reduction was 95%, the rolling texture of polycrystalline aluminum changed gradually from the copper type to the brass type as the magnesium content increased. The lowering of rolling temperature favored the component of the brass type texture. This was significant in the Al-Mg alloy. At 50% reduction, the main component of the rolling texture in pure aluminum and an Al-3%Mg alloy was {112} . However, when the reduction was larger than 50%, the orientation in aluminum and the Al-Mg alloy tended to approach to {146} . The transition from {112} to {146} occurred in the smaller reduction in the alloy than in pure aluminum.
