Fatigue Resistance of 2219 Aluminum Alloy and its Welded Joints

The paper presents fatigue test results for 2219 aluminum alloy specimens, cut from a plate 40 mm in thickness, under symmetric and pulsating loading cycle. It is shown that at stresses for above the endurance limit, the fracture of specimens has a multi-site nature and starts from their surface. At...
