استخدام فحوصات الكلال لتقييم الاجهادات المتبقية الناتجة من المعاملة الليزرية

الملخص EN

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).
