On the origin of superlattice stacking faults nucleation via climb of Frank partial in CoNi-based superalloys
Zhida Liang, Yinan Cui, Li Wang +4
High-temperature deformation in superalloys is governed by the cooperative glide-climb motion of dislocations. Superlattice stacking faults (SFs) in the gamma prime phase are predo…

High-Ti induced planar-fault transformation toward superlattice extrinsic stacking faults and microtwins in crept CoNi-based superalloys
Zhida Liang, Xiang Xu, Fengxian Liu +7
Controlling planar fault shearing mechanisms is key for improving the high-temperature creep performance of gamma prime-strengthened high-temperature superalloys. This work examine…

Segregation-driven cross-slip mechanism of shockley partials in the gamma prime phase of CoNi-based superalloys
Zhida Liang, Fengxian Liu, Xin Liu +3
In general, the cross-slip of superdislocations (a/2<011>) from {111} planes to {001} planes has been frequently observed in superalloys, accompanied by the formation of an antipha…
