Abstract

To improve the fatigue performance of 7050 aluminum alloy specimen with holes, the anti-fatigue strengthening mechanism of the process with ultrasonic vibration–assisted hole expansion strengthening (UVAHES) is investigated. The experiment of UVAHES 7050 aluminum alloy is performed, and the effects of ultrasonic vibration on the residual stress, surface roughness (Sa) and surface morphology of the hole wall of the specimen are studied, and the fatigue life and fracture morphology of the specimen are compared. The results show that the maximum residual compressive stress of the hole wall of UVAHES specimen is greater than that without ultrasonic hole expansion strengthening (WUHES). After the specimen is loaded, the hole wall stress is negatively correlated with the residual compressive stress, resulting in the maximum stress of the hole wall of UVAHES specimen is less than that of WUHES. The Sa of the hole wall of UVAHES specimen is 0.946 μm, which is less than that of WUHES and the without expansion strengthening (WES). The median fatigue life of UVAHES specimen is 1.5 times that of WES, and the median fatigue life of WUHES specimen is 1.2 times that of WES. The process of UVAHES, the number of times that the mandrel expansion strengthening the hole wall increases, the surface morphology of the hole wall improves, the residual compressive stress of the hole wall increases, thereby improving the fatigue performance of the specimen.
