Influence of ultrasonic impact treatment and working current on microstructure and mechanical properties of 2219 aluminium alloy wire arc additive manufacturing parts
Ultrasonic impact treatment (UIT) is considered to solve the defects of wire arc additive manufacturing (WAAM) components such as coarse grain size, large residual stress, and poor mechanical properties. In this paper, the effects of UIT on the microstructure and mechanical properties of 2219 alumin...
