The plausibility of < c plus a > dislocation slip on -12-11 planes in
JD Zhang and Y Zhang and JA El-Awady and YZ Tang, SCRIPTA MATERIALIA,
156, 19-22 (2018).
Here, the slip behavior of screw dislocations on first-order and
second-order pyramidal planes in Mg are systematically investigated.
Slip or/and cross-slip on six low Miller-Bravais-index planes, including
two new -12-11 planes that have hitherto not been considered possible,
are all observed. This new slip system has a low Peierls stress and
generalized stacking fault energy, suggesting that it might be an easy
mode. The active cross-slip and new slip system provide new insight into
the plasticity mechanisms of Mg. (C) 2018 Acta Materialia Inc. Published
