Detection of grain-boundary resistance to slip transfer using nanoindentation

Detection of grain-boundary resistance to slip transfer using nanoindentation

Nanoindentation measurements near a high-angle grain boundary in a Fe-14%Si bicrystal showed dislocation pile-up and transmission across the boundary. The latter is observed as a characteristic displacement jump, from which the Hall–Petch slope can be calculated as a measure for the slip transmissio...

Zusammenfassung:Nanoindentation measurements near a high-angle grain boundary in a Fe-14%Si bicrystal showed dislocation pile-up and transmission across the boundary. The latter is observed as a characteristic displacement jump, from which the Hall–Petch slope can be calculated as a measure for the slip transmission properties of the boundary.
