Analysis of a kink pair model applied to a peierls mechanism in basal and prism plane slips in sapphire deformed between 200C and 1800C
Miguel Castillo Rodríguez, Jacques Castaing, Antonio Muñoz Bernabé +2
A model based on dislocation glide controlled by the nucleation and propagation of kink pairs in a high Peierls stress crystal is revisited and modified to account for changes in d…

-AlO sapphire and rubies deformed by dual basal slip at intermediate temperatures (900C-1300C) -- II. dissociation and stacking faults
M. Castillo Rodríguez, J. Castaing, A. Muñoz +2
Sapphire and rubies (undoped and Cr-doped -AlO single crystals) have been deformed in compression at temperatures lower than those previously used in studies of dislocat…

Chromium hardening and Peierls mechanism for basal slip in sapphire at temperatures between 900 and 1500 C
Miguel Castillo Rodríguez, Antonio Muñoz Bernabé, Jacques Castaing +2
The plastic deformation of Cr3+ -doped a-Al2 O3 (ruby) with four distinct Cr concentrations has been studied at temperatures between 900 and 1500 C. The mechanical tests in…
