Abstract

Abstract: Crystallographic texture in metals influences material properties, e.g., r-value. In this work, a moderately strong <111> texture is obtained in AA5182-O through continuous-bending-under-tension processing followed by a recovery heat treatment from the initial weak cube <001> texture. EBSD scans confirm that the <111> texture is retained after heat treating. The processed material exhibits increased strength and reduced planar anisotropy, providing benefits to subsequent forming operations, compared to the as-received material. Crystal plasticity simulations confirm the texture change during deformation and predict the flow stress response. Such simulations can be used for stress superposition process design to intentionally manipulate material properties.
