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 sin²Ψ method of the X-ray diffraction technique indicates an improvement in the magnitude of compressive residual stress distribution after LSP. The hardness profile after LSP also shows substantial increment. The results suggested an improvement in the microstructural structure owing to the ultra-high strain rate deformation and refined grains. The High Score Plus software is used to analyse the crystallite size and microstrain of the alloy treated by different pulse energies.
