Fully reversed, total strain controlled low-cycle fatigue experiments were conducted on austenitic and martensitic CuZnAl alloys. The cyclic stress response of the austenitic CuZnAl was characterized by cyclic hardening within the first 10 cycles followed by cyclic stability up to the point of fracture. For the martensitic CuZnAl, cyclic hardening occurred from the first cycle with the process accelerating towards the point of failure. The cyclic strength coefficient, K', and the cyclic work hardening exponent, n', calculated for austenitic CuZnAl alloy was almost double the values calculated for the martensitic CuZnAl.
