Abstract
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.
期刊介绍：
Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
