摘要

电弧熔炼被认为是增材制造中打印材料与消耗材料比例最高的工艺之一。304不锈钢是一种突出的不锈钢，具有优异的耐腐蚀性和机械性能。采用电弧增材制造技术沉积304不锈钢部件，在相同和垂直方向上沉积后续层。用EBSD对两种条件下材料的力学性能、微观结构、XRD和显微织构进行了研究，并进行了比较。结果表明，两种条件下合金的力学性能基本一致，但微观组织和显微组织表现为沿同一方向沉积的等轴晶和沿垂直方向沉积的柱状晶。

Mechanical behaviour, microstructure and texture studies of wire arc additive manufactured 304L stainless steel

Abstract Wire arc melting is considered one of the most efficient processes in additive manufacturing in terms of material printed to material consumed ratio. 304 stainless steel is one of the prominent stainless steels with superior corrosion resistance and mechanical properties. 304 stainless steel components were deposited by wire arc additive manufacturing, depositing subsequent layers in the same and perpendicular directions. Mechanical properties, microstructure, XRD and microtexture studies were done by EBSD have been done for both the conditions and compared. Mechanical properties were found to be similar for both the conditions whereas the microstructure and microtexture showed equiaxed grains for depositing in the same direction and columnar grains for deposition in the perpendicular direction.
