W-10Cr-1Hf composite is a prospective material for fusion reactor. Precise defect analysis of materials has a significant effect on their performance and lifetime.
Using combination of AFM-in-SEM it was possible to distinguish all microstructural features, e.g. areas marked with a red color seemed to be pores in SEM, but in fact these spots were Hf inclusion between W- and Cr-grains. Therefore complex multi-modal in-situ characterization is needed for a better understanding of the materials’ structure.
Measurement modes: Topography, Nanoindentation
LiteScope benefits:
- Complex in-situ analysis (AFM, SEM, nanoindentation) of microstructure (features and defects) and mechanical properties
- Correlation of multiple channels (AFM + SE + BSE) from the same ROI
