Abstract A close analysis of the quenched Ni4Mo diffraction patterns of Chevalier and Stobbs (C-S)[1] shows not only that their conclusions, critical of our previous work, are unsubstantiated but that their data in fact support the multi-microdomain model previously proposed by our group [2–4]. Weak diffraction effects, previously observed in particular diffraction patterns [2–4], were undetected by C-S[1] and this is attributed to the unnecessary use of thicker foils by the latter. We also emphasise that real space lattice imaging studies are more likely to resolve the physical nature of short-range order than conventional electron diffraction studies as performed by C-S.
