Evolution of nanocavities in nc-SiC with different grain sizes
under tensile loading. Nanocavities for grain sizes d = 6 nm (a–c),
d = 4 nm (d–f), and d = 2 nm (g–i), have the strain values indicated
below the panels. Blue/grey color indicates the internal/external
surface of the cavities. (For interpretation of the references to colour
in this figure legend, the reader is referred to the web version of this
article.)
