Stacking fault energy in sapphire (x-Al/sub 2/O/sub 3/)
Journal Article
·
· Acta Metall.; (United States)
Stacking faults associated with climb-dissociated basal and prism plane dislocations after plastic deformation at elevated temperatures have been studied. In both cases, the fault vector is 1/3 <1010> and only the cation sublattice is faulted. The fault energy on (1010) and (1120) planes are between 0.1 and 0.25 J/m/sup 2/. One vacancy and two interstitial faults are possible in this structure; one of the interstitial faults, has the lowest energy.
