Effect of Surface Treatment with Laser Beam on the Residual Stress of Carbon Steel

Abstract

The aim of this study is to study the effect of laser treatment on residual stresses of carbon steel. The results showed the concentration of residual stresses in the laser treated steel compared to the treated steel (850) for 15 minutes and quench it with water. The results also showed the dispersion of residual stresses when the wavelength of the laser beam was increased.
