shows the nanoindentation-based load-depth plots for two different morphologies of B2 phase, viz. (a) nano-sized discs (in BCC phase) and (b) stringers (in FCC matrix) . It was specifically highlighted that B2 stringers show a lower hardness as compared to that of nano-sized discs (of B2 phase) owing to the lower Ni content of the former (Fig. and)) . Nevertheless, the hardness of B2
