Laser Peening Process and Its Impact on Materials Properties in Comparison with Shot Peening and Ultrasonic Impact Peening
The laser shock peening (LSP) process using a Q-switched pulsed laser beam for surface modification has been reviewed. The development of the LSP technique and its numerous advantages over the conventional shot peening (SP) such as better surface finish, higher depths of residual stress and uniform distribution of intensity were discussed. Similar comparison with ultrasonic impact peening (UIP)...
متن کاملOptimum Application of Ultrasonic Peening
A new advanced system for Ultrasonic Peening (UP) of materials, details and welded elements was developed recently. The UP produces a number of beneficial effects in metals and alloys. Foremost among these is increasing the resistance of materials to surface-related failures, such as fatigue, fretting fatigue and stress corrosion cracking. The beneficial effect is achieved mainly by relieving o...
متن کاملPeening Process Characterization and Optimization
This paper gives an overview of how to predict the intensity of the shot peening process using currently available technology. Methodology, tools, and software are also discussed. Real life examples are presented in the areas of optimization, troubleshooting, and process modeling.

متن کاملExperimental Study on Ultrasonic Shot Peening Forming and Surface Properties of AALY12
Ultrasonic shot peening (USP) studied. Several parameters (arc heights, surface roughness topography and micro hardness) with different parameters were measured. The research proposes curvature of shot peened sheet increases with time decreasing, while increases with pin diameter increasing, and curvature reaches a saturation level after a specific electric current. An empirical model of the re...
