“…3. Roughness is higher in the case of SP because the impingement of high-velocity shot particles generates overlapping microindentations on the surface (see Nordin and Alfredsson (2016)). In VP, roughness is relatively lower as it involves both the peening and burnishing effect.…”

Shot peening is a manufacturing process commonly used to increase fatigue life in components for the automotive and aircraft industry. In this paper the effect of shot peening is described for a case hardened gear steel. For gears there are three main factors from shot peening that influence fatigue life: residual stresses, microstructure and surface roughness. The paper describes an experimental series where these parameters were measured for common industrial shot peening settings. The aim was to show how several different measurement techniques and results correspond to each other for certain shot peening parameters. The aim was also to gather experimental results that can be used for verification of shot peening simulations. To simplify measurements and decrease variation, flat steel plates were used as targets. Residual stress, full width at half maximum (FWHM), retained austenite, surface roughness/topology, hardness and Barkhausen noise were measured and related to microstructural changes. The mean indentation diameter was measured for individual shots at low coverage of each intensity which was used to determine the average velocity of the media. The mean diameter and hardness of the shot peening media was also determined.

“…Gariépy et al (2017) estimated the distribution of shot velocity using the distribution of the size of the resultant indentations and performing numerical analysis on the residual stress. Nordin and Alfredsson (2016) used the indentation size to estimate the shot velocity and showed that the estimated shot velocity agreed with the measured values for small diameter shots. Guechichi et al (2013) clarified the relation between the peening strength measured using an Almen strip and the shot velocity for shot with an identical diameter and shot material.…”

Shot peening is applied to many manufactured parts to improve the fatigue strength of metals by introducing compressive residual stress near the surface. The distribution of compressive residual stress is mainly determined by shot diameter, shot velocity, angle of incidence, and peening time which affects coverage. In this study, the shot velocity was measured using particle image velocimetry (PIV) for shots fired at two different air pressures. The finite element method was used to analyze the residual stress distribution in a high strength aluminum alloy (A7075-T6) plate during shot peening. The shot was accelerated up to a standoff distance of approximately 200 mm from the nozzle outlet. The measured maximum shot velocity increased proportionally to the air pressure to the 0.59th power. The analyzed residual stress distributions using measured shot velocity with PIV through the thickness of the specimen agreed well with the measurements under two types of peening conditions with differing air pressure and angle of incidence. The shot velocity measurement technology and the numerical model for analysis of the shot peening residual stres were both validated in this study.
