“…The dispersion of these phases in the material resulted in precipitation strengthening of the buildup wall. However, according to reports in the references [1] and [15,16], the main strengthening mode of this material is solid solution strengthening, mainly the entry of aluminum atoms into the crystal of iron. As a whole, the hardness of the three samples is II > III > I, which is related to the difference in grain size.…”

“…The WAAM process usually uses single feed wire and produces a deposited structure of the same composition as the wire. Recently, the WAAM using gas tungsten arc welding (GTAW) process has been used to manufacturing binary phase intermetallic materials, such as gamma titanium aluminide [14] and Fe 3 Al based iron aluminide [15]. Chen et al [15] completed the preparation of Fe-Al alloy by WAAM process, and made an in-depth study of its microstructure, chemical composition, and mechanical properties.…”

In this study, wire and arc additive manufacturing (WAAM) was used to form SUS304/aluminum alloys. The buildup wall was well shaped using a pulse current consisting of a base current of 150 A and peak current of 200 A and a 0.2 m/min travel speed. Metallographic observation revealed that the original grains were columnar grains and transformed into equiaxed grains in the top area. The increased content of alloying elements in the fused layer improved the hardness of the buildup wall. The buildup wall formed using pulsed current exhibited improved anti-electrochemical corrosion performance when compared with that formed using constant current. The tensile strength of the alloy decreased but its elongation increased compared with those of Fe-Al alloys. The tensile fracture along the fusing direction was plastic fracture. However, the tensile fracture perpendicular to the fusing direction consisted of a combination of plastic and brittle fracture.

“…The width of the buildup wall is approximately 10mm and the average height is 47mm, with some substrate distortion being present. In order to remove the inhomogeneous microstructure and element distribution in the very top deposition layer, as indicated in the preliminary studies [28,29], an additional remelting process (arc heating without deposition) was applied. The extraction locations for various material samples are marked in Fig.…”

“…Recently, a WAAM system using the gas tungsten arc welding (GTAW) process has been used to in-situ fabricate binary phase intermetallic materials such as gamma titanium aluminide [27] and Fe 3 Al based iron aluminide [28] with pre-designed chemical composition. In the case of iron aluminide, pure iron and aluminum wires are fed separately into a single molten pool through a twin-wire feeding system with a specific wire feed ratio, in order to control the composition of the deposited material.…”

Due to the inherent properties of the process, arc-based generative manufacturing offers the possibility, of specifically applying different material properties locally. One possibility to realize this is the use of different materials. Three approaches are presented to illustrate this option. First, anisotropic behavior in the welding direction is generated. For this purpose, a FeNi36 is specifically combined with a low-alloy ultra-high-strength fine-grained structural steel filler metal. It will be shown that the integral component properties can be specifically adjusted in the welding direction. In addition, the metallurgical and welding characteristics will be discussed. As a second possibility, the use of well plasticizable materials to locally increase the material strength under cyclic loading with locally notched components is presented. For this purpose, an austenitic FeNi36 with good plasticizability and a good yield strength ratio for the application was applied to a fillet weld of a high-strength fine-grained structural steel in the weld seam toe. It is shown that the tolerable cyclic load can be improved by 35% by this procedure. Thirdly, it is shown that the required thickness of corrosion protection layers can be reduced by 50% through a targeted production sequence in arc-based generative manufacturing.
