Forthcoming article in Journal of Applied Crystallography
Journal of Applied Crystallography covers a wide range of crystallographic topics from the viewpoints of both techniques and theory. The journal presents articles on the application of crystallographic techniques and on the related apparatus and computer
Energy-resolved small-angle neutron scattering from steel
A new analysis technique for energy-resolved small-angle neutron scattering is proposed. The precipitate dimensions in steel determined from fitting the observed neutron attenuation spectra agree with those calculated from conventional fitting of the corresponding small-angle neutron scattering profiles.
Debye–Waller coefficient of heavily deformed nanocrystalline iron
Extensive deformation of an iron alloy powder increases the static disorder contribution to the thermal factor, with an increase of ∼20% in the Debye–Waller coefficient observed by both X-ray diffraction and extended X-ray absorption fine structure. Molecular dynamics simulations shed light on the underlying mechanisms, confirming the major role played by the grain boundary.
