The onset of strain localization in a copper single crystal, oriented for single slip, and cycled at a constant plastic strain amplitude corresponding to the low end of the plateau in the cyclic stress-strain curve, has been explored by inteferometry and analysis of hysteresis loops.

A study of fatigue hardening in single crystals of pure copper shows that, before saturation, stress-strain loops can display workhardening rates of about a third of the elastic shear modulus. These rates exceed tensile workhardening rates by roughly two orders of magnitude. This suggests that there
