- Abstract
- Serial section focused ion beam tomography was performed for a three-dimensional reconstruction of the microstructure of defects associated with the formation of fatigue cracks in samples destroyed during fatigue tests. The geometric parameters of defects containing Hf, Nb, Ti, Al, and Ni identified during 3D reconstruction were determined. The morphology of individual particles is represented by a set of shapes that form flat (carpet-like) conglomerates up to tens of microns in size, which cannot be detected by non-destructive testing methods. The revealed morphological features make it possible to propose a set of measures to increase the service life of parts made of granulated heat-resistant nickel alloy EP741NP, which is an important practical result of the study.
