Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the specific Young’s modulus of a given crystallographic direction. After normalizing by elastic stiffness, the magnitude of average lattice distortions increased reasonably in accordance with age hardening. %U https://journal.issiran.com/article_6340_1aa06f9a02f9714df2663a7dfa137340.pdf
