The local interfacial structure and bonding at the rhombohedral twin interface in α-Al 2 O 3 (corundum) was studied by means of first-principles electronic-structure calculations based on the local density functional theory. Two sets of geometrical interface models were selected, one with a terminat

The properties of sapphire (a-Al 2 O 3 ) predeformed at T = 1450 °C by h1 0 1 0i{1 2 1 0} prism plane slip and subsequently deformed in h1 2 1 0i(0 0 0 1) basal slip between 1050 and 1250 °C were investigated. The critical resolved shear stress in basal slip was increased with respect to the non-pre
