α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): I. Dislocation organization
(Elsevier, 2009)Under a load orientation that hinders twinning and impedes fracture, sapphire and Cr-doped α-Al2O3 single crystals (rubies) were deformed from 1500 °C to slightly above the brittle to ductile transition temperature of 900 ... -
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): II. Dissociation and stacking faults
(Elsevier, 2009)Sapphire and rubies (undoped and Cr-doped α-Al2O3 single crystals) have been deformed in compression at temperatures lower than those previously used in studies of dislocations in the basal slip plane. Above 1400 °C, several ...
