Abstract
This paper reports metallographic evidence of strain markings in high-purity aluminum (99.998 pct), hitherto unobserved, and a study of their crystallography. Some incidental observations tend to provide indirect evidence of a close relationship between strain markings and annealing twins, to clarify the peculiar behavior of aluminum in its reluctance to form banded annealing twins, and to indicate that the type of localized strain at the slip interfaces, which are responsible for the etching effects that render strain markings visible, consists of a twinning displacement.
