Decryption of diffraction patterns with complex crystal structures using 3D-model of the reciprocal space of crystal lattices

When doing diffraction studies of multiphase alloys, it is necessary to decrypt the diffraction patterns comprising a great number of phase reflexes formed by crystallographic equivalently oriented in the matrix phase separation. Similar problems can be solved by constructing a three-dimensional space model of reciprocal lattice points of the matrix and phase, taking into account all crystallographic equivalent phase orientations in the matrix. The central section of such a model corresponds to the electron-diffraction pattern, received in a transmission electron microscope. It is possible to obtain any zone axis in the section if the model is properly rotated in the reciprocal space. The ability to control the reflection of crystallographic equivalent phase orientations in the model makes it possible to split the reflexes of the various phases and their crystallographic equivalent orientation in any zone axes.
