摘要：

The wire arc additive manufacturing (WAAM) was employed to fabricate the AZ61 alloys via different fabrication parameters. The microstructure, including grain size and porosity, varies with the processing conditions, which significantly influence the mechanical properties of the fabricated materials. The superior microstructure with fine grains and reduced porosity was achieved via fabrication parameters with current of 130A, voltage of 12.5 kV and wire feed speed of 820 mm/min, providing exceptionally excellent comprehensive mechanical properties.
