Basal slip latent hardening by prism plane slip dislocations in sapphire (α-Al2O3)
(Elsevier, 2010)
The properties of sapphire (α-Al2O3) predeformed at T = 1450 °C by 〈〉{} prism plane slip and subsequently deformed in 〈〉(0 0 0 1) basal slip between 1050 and 1250 °C were investigated. The critical resolved shear stress ...
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 ...
