Using Fatigue Testing to Evaluate Residual Stresses Resulting From Laser Treatment for ١٠٦٠ Aluminium–Alloy

Abstract

The aim of the present study is to estimate the residual stresses throughfatigue testing of ١٠٦٠ Aluminium–Alloy. The experimental work has beencarried out under variable amplitude tests with and without laser treatment(the surface of the alloy is subjected to pulses of laser then without laser). Theconclusions derived from this study are:- The residual stresses are of thetensile type which lead to deterioration of mechanical properties and fatiguebehavior, and that the value of the residual stresses is less than oneMegapascal (< ١MPa).
