Figure 2
(a) 2D diffraction patterns (the {110} reflection) for nanocrystalline Ta at different strains (∊xx or simply ∊) under isothermal compression (DAC). (b) Distribution of ψ on the 2D diffraction patterns for the transverse geometry. (c) Corresponding dm versus plots. The solid curves in (a) and (c) denote fitting based on equation (4). |
