3D mosaicity of a single-crystal nickel-based superalloy by lab-based diffraction contrast tomography
The 3D microstructure of a second-generation single-crystal nickel-based superalloy , René N5, has been analyzed using laboratory-based X-ray diffraction contrast tomography (lab-based DCT). This experiment has demonstrated the precise capabilities of lab-based DCT in resolving subgrain boundaries with a misorientation angle of less than 1°, achieving an angular accuracy as fine as 0.1°. The performance of the lab-based DCT has been compared with standard and widely used electron backscatter diffraction (EBSD) analysis. Obtaining the 3D microstructure non-destructively enabled the segmentation of the network of nickel-based single-crystal dendrites, opening up new opportunities for studying crystal mosaicity.
