description: This paper presents an approach to the quantitative analysis of electron backscattered diffraction data. The crystal curvature was analyzed on the experimental data basis. The technology of approximation of experimental results is studied. A specific software implementation has been developed to determine the volume fraction of bainite in martensitic steel. Tasks that were solved during the study: 1. Study of physical concepts of martensitic and bainitic transformations. 2. Identification of the dependence between the cooling rate and the volume fractions of the martensitic and bainitic phases in the sample. 3. Development of a program for analyzing the crystal curvature. 4. Estimation of volume fractions of the bainitic phase in martensitic steel. The work was carried out on the basis of electron backscatter diffraction data. Taking into account the laws of the kinetics of bainitic and martensitic transformations, the distributions of the GAM parameter characterizing the crystal curvature are approximated by the lognormal function and on this basis the volume fractions of phases are found.
