Fig.4. The modified Williamson-Hall plots obtained by neutron diffraction and synchrotron XRD (β=(1.5φs+φt)/a, where a is the lattice constant; φs and φt are the probability of finding a stacking fault and a twin boundary in {111} planes, respectively; Whkl is a factor to scale the faulting-induced peak broadening at different {hkl} reflections; Cˉ is the average dislocation contrast factor)
