Abstract. The paper considers the possibility of studying the fine structure of samples
made of niobium alloy 5 VMC (grade 5B2MC-2), which underwent internal nitriding by X-ray
diffraction analysis.The calculation of the dislocation density, which represents one of the
parameters of the fine structure using various techniques, is shown. Its influence on the possible
modes of internal nitriding is considered.

Key words: X-ray diffraction analysis, dislocation density, hardening of niobium alloys.
