Due to a lower symmetry of the tetragonal C11b structure when compared with the cubic body-centered cubic lattice, the 1/2<331] dislocation cores were split asymmetrically contrary to the 1/2<111> body-centered cubic dislocations. This had essential impact on their behaviour and, consequently, on mechanical properties. Various types of dislocation dissociations were analyzed in the frame of anisotropic elasticity with the help of the data from ab initio calculations of γ-surfaces for generalized stacking faults.
