$\alpha$-Al${}_2$O${}_3$ sapphire and rubies deformed by dual basal slip at intermediate temperatures (900C-1300${}^{\circ }$C) -- II. dissociation and stacking faults

M. Castillo Rodríguez, J. Castaing, A. Muñoz +2

Sapphire and rubies (undoped and Cr-doped $\alpha$-Al${}_2$O${}_3$ single crystals) have been deformed in compression at temperatures lower than those previously used in studies of dislocat…
