The Features of Structure Formation in Chromium-Nickel Steel Manufactured by a Wire-Feed Electron Beam Additive Process

Anisotropy of the tensile properties in austenitic stainless steel obtained by wire-feed electron beam additive growth

“…3 a, b). The formation of high-temperature ferrite in austenitic SS during the AM process was noted in many studies [11][12][13][14]16,17], including those for stable AISI 316L steel [14,8], in which the nickel content in the initial material is higher than in the investigated steel (12 % versus 9 %).…”

“…Such complex thermal cycles could lead to anisotropy and heterogeneity of the microstructure and mechanical properties of the billets. Regarding austenitic SS obtained by different AM methods, the anisotropy of mechanical properties is described, for instance, for AISI 304, 304L, 316L steels in [11][12][13][14][15]. This could be associated not only with the heterogeneity of the formation of a grain structure and microstructure, but also with a change in the phase and elemental composition of the additively manufactured billets [11][12][13][14][15].…”

Review on electron beam based additive manufacturing

“…In the case of a wire-based process, few studies are found compared to powder-bed-based process. It has been seen that most of the studies for this process are still for the realization of new materials such as for titanium, stainless steel, Inconel, aluminum, etc., which are focused on material and mechanical characterization (Yu et al, 2009;Kolubaev et al, 2018). For a wire-based process, residual stress has always been a problem due to large heat deposition, which has also been studied for the EB-based process (Denlinger et al, 2015;Tarasov et al, 2018).…”
