Abstract
The aim of the present study is to estimate the residual stresses through
fatigue testing of ١٠٦٠ Aluminium–Alloy. The experimental work has been
carried out under variable amplitude tests with and without laser treatment
(the surface of the alloy is subjected to pulses of laser then without laser). The
conclusions derived from this study are:- The residual stresses are of the
tensile type which lead to deterioration of mechanical properties and fatigue
behavior, and that the value of the residual stresses is less than one
Megapascal (< ١MPa).
