Abstract

Nanoindentation measurements are carried out in the fatigue plastic zone in the 2024 T351 alloy. It is shown that variations in hardness, plastic work and plasticity index show typical evolution permitting the identification of cyclic and monotonic plastic zones. The measured values are comparable with theoretical estimations. A calibration test permits the evolution of strains in the plastic zone.
