… of dislocations at the cellular boundary played a key role in the interfacial strengthening effect.
… the neighbouring cellular sub-grain, the cellular boundary acted as the high-angle grain …

… To gain further insights on cells formation and precipitate strengthening mechanisms, we
performed three-dimensional DD simulations. The results are summarized in Fig. 10. …

… to a combination of grain boundary strengthening and dislocation strengthening [11,12]. In
contrast, Wang et al. [13] reported that the biggest strengthening contribution in AM processed …

… This work revealed the internal strengthening mechanisms of a LPBF-ed superalloy with
heterogeneous cellular and grain structures. Two post-heated samples with different cellular …

… -deformation-induced strengthening reported by Zhu et al. [56]. They proposed a strengthening
mechanism based on the back-stress model at the boundary in heterogeneous hardness …

… As the cellular substructure becomes more perfect, the resistance to shear increases. The
barrier strengthening mechanism is realized in the cellular … of misoriented cell boundaries and …

… While there are a number of works describing the strengthening mechanisms in L-PBF-…
The fine cellular structure together with melt pool boundaries were clearly visible in the as-…

… The entangled dislocations and segregated elements at cellular substructure boundaries
exhibit limited thermal stability, beginning to disintegrate at 400 C and complete by 1000 C. In …

… Quantitative analysis revealed that the cellular structures contribute significantly to the
enhanced strength through dislocation hardening rather than cellular boundary strengthening. …
