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…

Scale-bridging dislocation plasticity in MgO at room temperature
Jiawen Zhang, Zhangtao Li, Yuwei Zhang +7
Dislocations in ceramics have recently gained renewed research interest, in contrast to the traditional belief that ceramics are inherently brittle. Understanding dislocation mecha…

Stable crack propagation in dislocation-engineered oxide visualized by double cleavage drilled compression test
Oliver PreuÃ, Zhangtao Li, Enrico Bruder +4
Understanding crack tip - dislocation interaction is critical for improving the fracture resistance of semi-brittle materials like room-temperature plastically deformable ceramics.…
