Advances in Micro-Scale Laser Peening Technology
Recent advances in laser peening technology, also known as laser shock processing (LSP) are reported. Specific emphasis is placed on its development in the micro scale regime. LSP imparts desirable residual stress distributions into the target material in order to improve the fatigue life of the material. In modeling improvements, plasma expansion is modeled as laser supported combustion wave, ...
متن کاملLaser 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 کاملInternational Conference on Laser Peening and Related Phenomena
The heat-resistant steel after aluminized was treated by laser shock processing (LSP) with high power Nd:YAG laser, and then was tensile tested at 400 . The effects of the high °C -temperature behavior after LSP were analyzed from residual stress and fracture organization. The results showed that the yield strength and tensile strength of heat-resistant steel after aluminized were improved obvi...
متن کاملSystematical Characterization of Material Response to Microscale Laser Shock Peening
The response of materials after microscale laser shock peening (mLSP) was experimentally characterized and compared with the theoretical prediction from FEM analysis in microlength level. Since mLSP is predominantly a mechanical process instead of a thermal process, the characterization focuses on mechanical properties and associated microstructures. An X-ray microdiffraction technique was appl...
