The plastic deformation of Cr 3+ -doped ␣-Al 2 O 3 (ruby) with four distinct Cr concentrations has been studied at temperatures between 900 and 1500 • C. The mechanical tests indicate that the processes of dislocation multiplication and the adjustments of the slip velocity of these dislocations to t
