Figure 3 Nucleation of dislocations in the PCNLDP
HEAs. (a–e) Perspective
view of nucleation of partial dislocations in the FCC lamella. In
the figures, the blue atoms in the lower layer represent HCP nano-lamella,
the red atoms in the upper layers denote nucleated stacking faults,
the atoms colored with white represent grain boundaries and dislocation
cores, and the atoms with a perfect FCC lattice in the upper layer
are deleted for clarity. The Shockley partial dislocations are colored
with green lines. (f) Critical stress for nucleation of Shockley partial
dislocation as a function of phase volume fraction.
