摘要

研究了超声辅助和非超声辅助下WAAM钢壁力学行为的各向异性。在没有UA的情况下，WAAM生产的样品存在力学行为的各向异性，而在UA条件下，WAAM生产的样品没有观察到力学行为的各向异性。推测不加UA的WAAM试样力学行为各向异性的原因是α→γ→α相变过程中形成的晶粒继承了柱状晶粒的织构。在WAAM过程中，超声辅助降低了柱状晶粒的织构，使其力学行为更具各向同性。

Anisotropy in the Mechanical Behaviour of the Low-carbon Steel Wall Produced by Wire Arc Additive Manufacturing without or Under Ultrasonic Assistance

Anisotropy in the mechanical behaviour was studied in steel wall produced by WAAM under or without ultrasonic assistance (UA). Anisotropy of the mechanical behaviour was found in sample produced by WAAM without UA and was not observed in sample manufactured by WAAM under UA. It was assumed that the reason for the anisotropy of the mechanical behaviour in sample produced by the WAAM without UA was the grains formed during the α → γ → α transformation inherited the texture of the columnar grains. Ultrasonic assistance during WAAM decreased the texture of columnar grains, as a result, the mechanical behaviour was more isotropic.
