Stacking Structure and Phase Stability in Ni-based GCP Compounds

Plastic deformation behavior of Mg12YZn with 18R long-period stacking ordered structure

“…This may be related to the reason why the plastic behavior of the LPSO-phase due to slip on (0001) is not significantly different from the behaviors in pure Mg, and its solid solutions. Similar results were previously reported in Ni-based LPSO crystals [24][25][26], in which the basal slip occurs easily with almost the same CRSS at low temperatures irrespective of the stacking sequences.…”

Plastic deformation behavior of Ni3(Ti0.7Nb0.3) single crystals with D019 structure

“…With regard to the controlling factors of the YSA behavior accompanying the K-W locking, we have previously reported that the absolute value of the anisotropy of the APB energy strongly affects the peak stress of the YSA [15]. Another potential controlling factor could be the relation between the mobility of dislocation on the prism plane and the YSA behavior of basal slip; this is because the K-W locking process involves the thermally activated cross-slip from the (0001) primary slip plane onto the f0110g prism plane.…”

“…We recently determined that the peak stress of YSA in those GCP compounds is controlled by the absolute value of the anisotropy of the APB energy between the slip plane and the cross-slip plane via the change in the locking probability of the screw dislocations [15]. Since the K-W locking process involves microscopic cross-slipping of the screw dislocations, the relation between the mobility of dislocation on the cross-slip plane and the YSA behavior by basal slip is of considerable interest.…”
