Abstract Scope |
The aluminum alloy 7010 is widely used in the aerospace industry due to its comparatively light weight and high strength. Shot peening is an important surface modification procedure for structural materials meant for improving the fatigue life. The surface properties can be further enhanced by changing the temperature of the surface during the process of peening. In this study, shot peening at room and at high temperatures ranging from 100°C to 300°C was performed at three Almen intensities: 0.10, 0.15, and 0.20 mmA, on cylindrical specimens of AA7010-T7452. The influence of the process on surface roughness, residual stresses, hardness, and microstructure was investigated. The results showed that the surface roughness increased with temperature of peening. An optimized peening temperature was identified from the variation of hardness and residual stresses. In-depth microstructural characterization of the surface after peening helped in understanding the surface integrity properties in greater detail. |
