Effects of ultrasonic rotating extrusion assisted wire arc additive manufacturing on the microstructure and mechanical properties of 5356 aluminum alloy by Rongtao Zhu, Liang Zhang, Longhan Duan, Zhaofeng Liang, Chuang Li, Bo Yuan, Peng Du, Zhiwen Xie, Yaping Zhang

“…Despite this, the presence of porosity defects, coarse surface grain sizes, and the clustering of precipitated phases in WAAM-produced Al alloy samples have been identified as detrimental to their mechanical properties, rendering them inadequate for contemporary service requirements. In this investigation, an innovative approach termed Ultrasonic-Rotating Extrusion-Wire Arc Additive Manufacturing (U-RE-WAAM) was proposed, which integrates the synergistic effects of ultrasonic and mechanical force fields into the WAAM process. …”
