English Abstract

This paper investigated the influence of shot peening on (AA2024-T4) at different times of peening (2, 4, 6, 8, 16 and 24 min).

It was observed the shot peening process leads to improve fatigue strength up to certain value and then fatigue life decrease.

The best value of fatigue strength was (385 MPa) that obtained at 16 min.

This improvement in fatigue life due to residual compressive stresses introducing on alloy's surface.

Other mechanical test as hardness, roughness and tensile tests also have been investigated.

The highest vales of surface hardness and roughness were (394HVN)) and (8.1 μm) that obtained at (24min) times of shot peening process.
