Fig. 4

a–f Transmission electron microscopy (TEM) images of deformed microstructure. a Dislocations bowing when bypassing the cross-section of hP24 marked by red arrows. b Massive dislocation interactions and homogeneous deformation substructures indicated by a blue arrow. c An enlarged image of the marked area in (b) showing hP24 acting as obstacles. d Highly faulted hP24 precipitates with more evident hcp diffraction pattern of hP24 structure. e Partial dislocations emitted from grain boundaries (GBs) leading to extended stacking faults (SFs) in L12. f L12 transforming to hP24 with the aid of deformation-induced SFs.
