The stability of super-partial dislocations, and their kink pairs, on various slip planes was considered. The energy factor and the line tension factor were calculated here by using Stroh’s sextic formalism between room temperature and 1173K. The {111} cross-slip of <101]-type super-dislocations occurred at moderate temperatures, while {010)-type cross-

slip was observed at high temperatures. The elastic anisotropy effect was studied in order to understand the temperature-dependent cross-slip behavior of super-partial dislocations. The elastic stability of super-partials was checked on the (111) and (010) planes. The interaction energy between a kink pair formed on a super-partial was also calculated for various cross-slip planes.
