采用电弧增材制造 (WAAM) 通过不同的制造参数来制造 AZ61 合金。微观结构，包括晶粒尺寸和孔隙率，随着加工条件的变化而变化，这显着影响所制造材料的机械性能。通过电流 130A、电压 12.5 kV、送丝速度 820 mm/min 的制造参数，实现了细晶粒和降低孔隙率的优异微观结构，提供了极其优异的综合机械性能。
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.
