Extended Data Fig. 5: EVPSC modelling results of nickel.
From: High-pressure strengthening in ultrafine-grained metals
a, Comparison between simulated Q(hkl) curves versus pressure and measured Q(hkl) values (solid symbols) obtained from experiments. b, Simulated texture of nickel at the highest strain (pressure). c, Simulated differential stress of nickel versus plastic strain during zero pressure compression. d, Extrapolated yield strength of nickel at ambient conditions without GB sliding. The size-strengthening trend is consistent with that shown in Fig. 1b, although the strength of 40-nm-grain-size nickel obtained with EVPSC is slightly lower.
