The initial stage of the fatigue process — fatigue hardening — is studied for three CuZn alloys with different stacking fault energies in the region of low stress amplitudes (lifetimes of order 10 5 cycles and higher). The study involves both measurements of the mechanical properties in the microstrain region and transmission electron microscopy. All measurements confirm the strong influence of the stacking fault energy on the course of the hardening. Fatigue hardening arises from both short‐range and long‐range stress fields. The contribution of the long‐range stress fields to the total hardening decreases with decreasing stacking fault energy.
