Characterization of Non-Metallic Inclusions in Bearing Steels by Means of Focused Ion Beam
SourceThe feasibility and benefits of focused ion beam–scanning electron microscopy (FIB-SEM) tomography for the characterization of non-metallic inclusions in bearing steels was evaluated. The technique enables precision, essentially stress-free, serial milling of microstructural features, from which a three-dimensional (3D) profile can be reconstructed. 3D imaging of the inclusions using FIB-SEM has provided relevant information about the inclusion connectivity (bonding/debonding between the inclusion and the steel matrix), the real shape and size of the inclusions, and the spatial distribution information of the inclusion. Additionally, the analysis has provided some insights on their inner structure (presence of cracks, etc.).
