The generalized-stacking-fault energies are calculated to illustrate the
dissociation of < c + a > dislocation on pyramidal I plane in magnesium.
The gamma surfaces of *10 (1) over bar1* plane and its adjacent planes
*30 (3) over bar4* and *30 (3) over bar2* are presented using Liu
embedded-atom-method potential method, and one possible dissociation
path of 1/3 < 11 (2) over bar3 > dislocation on *10 (1) over bar1* plane
with minimum energy is predicted. Meanwhile, another two reasonable
dissociation paths of 1/3 < 11 (2) over bar3 > dislocation successively
on *30 (3) over bar4* and *30 (3) over bar2* planes are also proposed.
Moreover, based on molecular dynamics simulations of magnesium single
crystals under c-axis compression, the possible slip path is further
examined and discussed.
