Uncharacteristic evolution of copper type texture in the presence of shearable precipitates

Abstract

Abstract In the present work, development of rolling texture in the presence of shearable precipitates is analyzed using age hardenable aluminum magnesium silicon alloy (AA 6061) and aluminum-copper-lithium alloy (AA 2195). A characteristic Brass type texture evolves upon rolling of AA 6061 alloy containing β’’ (Mg5Si6) precipitates, whereas an unexpected Copper type texture develops upon rolling of AA 2195 alloy containing T1 (Al2CuLi) precipitates. The present work highlights that rolling texture evolution in the presence of shearable precipitates cannot be generalized and depends strongly upon the shearing propensity of these precipitates.
