Plastic deformation of CaF₂ single crystals

Engineering dislocation‐rich plastic zones in ceramics via room‐temperature scratching

“…In fact, quite some single‐crystal ceramic materials can be plastically deformed at room temperature in bulk compression 14–19 . Yet, these approaches usually produce plastic zones that contain only narrow slip bands (e.g., several or tens of micrometers in width 20 ) confined to discrete regions in bulk crystals.…”

“…13 In fact, quite some single-crystal ceramic materials can be plastically deformed at room temperature in bulk compression. [14][15][16][17][18][19] Yet, these approaches usually produce plastic zones that contain only narrow slip bands (e.g., several or tens of micrometers in width 20 ) confined to discrete regions in bulk crystals. This not only limits the available dislocation-rich region for further testing but also leads to inefficient use of the entire crystals, which usually are very expensive.…”
