    Abstract: This paper presents the after effect of laser shock peening (LSP) on AA2024 alloy specimen irradiated with the L-Spiral scanning pattern at different pulse energies. The surface morphology indicates an increase in surface roughness after LSP. The X-Ray diffraction analysis of the LSP treated specimens were compared with the untreated specimen. The ... Show More
