“…The works [1,2,[7][8][9][10][11] testify that impact strength tests are often appointed as acceptance trials for structural materials. Meeting the requirements both in strength and impact strength is the principally important step for the most structural materials; unfortunately, these properties are usually mutually exclusive [11].…”

“…The process of gas metal arc welding by metallic electrode (GMAW) using electrode wire AWS ER70S-6 for creation of single-pass construction was described in the work [8], the obtained results showed that this material has high impact strength and rather plastic behaviour. It was revealed [8,9], that the critical range of cooling rates with large volumetric part of TiO 2 inclusions in austenite composition leads to forming of needle ferrite in steel welding seams and, respectively, to decrease of dispersion of impact strength values.…”

The results of study of impact strength of C-Mn-Si composition metal after wire-arc additive manufacturing (WAAM) are presented. It was established that destruction of the samples of such composition at the temperatures below tough-brittle transition occurs both via tough and brittle mechanisms. The samples manufactured in the direction along built-up welding are characterized by essentially lower impact strength comparing with those manufactured in vertical direction of samples cutting. Impact strength of the samples made of 09G2SA standard steel is substantially lower than for C-Mn-Si composition metal which was obtained via additive technology. Fractographic analysis of fractures for C-Mn-Si compositions manufactured via additive technology using carbon dioxide and gas mixture displays tough pit destruction type. The samples with high impact strength are characterized by forming of cleavage facets after tough crack propagation to the sample middle, what is accompanied by significant widening opposite to a notch and narrowing under a notch. The samples with low impact strength are characterized by forming of brittle fracture directly under a notch without essential sample plastic deformation. It is shown that built-up welding with partial or complete recrystallization of rolls is required for forming of cold-resistant metal structure. In this case, order of rolls location, heat input and parameters of welding conditions make the direct effect on shape, geometrical dimensions, fusion penetration and number of rolls, as well as on size and morphology of the structural components, percent relation between cast and recrystallized microstructure of seam metal. The complex of these factors finally determines structural state and cold resistance of seam metal.

The additive manufacturing technique is becoming popular and promising in recent years. Some steel ER70S-6 specimens were produced by wire arc additive manufacturing. Before the tensile tests, 3D X-ray computed tomography was applied to detect the presence of internal defects due to the production process. Static tensile tests were performed in order to analyze the influence of the different directions (deposition and layer stacking directions) on the mechanical properties. The digital image correlation technique was applied during the tests for detecting the displacement and strain fields, while infrared thermography was applied for detecting the temperature field of the specimen surface. After the mechanical tests, scanning electron microscopy was employed to analyze the fracture surfaces of the specimens. The results showed the presence of small defects that did not affect the mechanical properties of the specimens and no significant anisotropy was detected in the two directions (deposition and layer stacking directions).
