Kikuchi pattern dataset from wrought and as-built additively manufactured superalloys

This dataset provides high-resolution Kikuchi diffraction patterns and associated orientation mapping data collected from both wrought and as-built additively manufactured (AM) Inconel 718 superalloys. The dataset includes raw electron backscatter diffraction (EBSD) patterns stored as .tif images and organized through .up2 metadata files, along with processed orientation data in .ang format. These measurements were acquired using a high-sensitivity EBSD detector over large scan areas, enabling detailed spatial resolution of microstructural features such as grain orientations, subgrain boundaries, and processing-induced texture. The dataset supports a range of applications, including machine learning for pattern recognition and the development of robust indexing algorithms. By including both wrought and AM material states, this dataset offers valuable insight into the influence of manufacturing route on crystallographic texture and cellular dislocation structure in Inconel 718, a critica...,
Materials and Sample Preparation:
Three different nickel-based superalloys were used in this study: a wrought recrystallized Inconel 718 (30 minutes at 1050°C followed by 8 hours at 720°C) with chemical composition of (wt.%) Ni – 0.56% Al – 17.31% Fe – 0.14% Co – 17.97% Cr – 5.4% Nb + Ta – 1.00% Ti – 0.023% C – 0.0062% N; a 3D-printed Inconel 718 by DED (as-built) and a dynamically recrystallized Waspalloy (heat-treated) characterized by a necklace microstructure. The 3D-printed material was produced using a Formalloy L2 Directed Energy Deposition (DED) unit utilizing a 650 W Nuburu 450 nm blue laser capable of achieving a 400 μm laser spot size. Argon was used as the shielding and carrier gas, and the specimen remained in its as-built condition. The chemical composition is in wt.%: Ni – 0.45% Al – 18.77% Fe – 0.07% Co – 18.88% Cr – 5.08% Nb – 0.96% Ti – 0.036% C – 0.02% Cu - 0.04% Mn - 0.08% Si - 3.04% Mo. All samples were machined by EDM as flat dogbone samples of gauge section 1 × 3..., # Kikuchi pattern dataset from wrought and as-built additively manufactured superalloys
