Figure 9. SEM fractographs of the fracture toughness samples tested in (a) Air (b) In-situ experiment with current density 20mA/cm 2 . The fractographs show that the surface is completely dimpled consisting of coalesced micro-voids, in case of fracture toughness tests carried out in air as compared with intergranular nature of fracture surface shown for the in situ experiment with electrochemical charging. The contrast of the change in fracture mode from ductile micro-void
