This work is based on a well-known method of diffraction patterns indexing – a method of paired reflexes. This paper presents a modified program for indexing electron diffraction patterns «DiffraCalc», which allows to decode the diffraction patterns obtained from the phase inclusions, considering the chemical composition. This procedure helps to determine the crystallographic structure of the considered phase. When the elemental composition of the inclusion obtained from containing sample site is taken into account, decoding of the diffraction pattern can be made. The method of EDX-spectrometry is usually used in case of steel researches, because this method is more sensitive to heavy elements which are defining in the formation of phase components in iron-based alloys.
The analysis of chemical composition of the selection has to be done to determine the crystalline type of phase inclusion within the micro-diffraction method. The micro-diffraction method in transmission electron microscopy allows to determine the crystalline types of phase components in alloys, that is necessary to calculate the effect on mechanical properties of the materials.
