Abstract
Neutron radiography using monochromatic neutron radiation makes it possible to visualize the diffraction contrast between different phases in a polycrystalline material due to the difference in the attenuation of the neutron beam intensity in these phases due to coherent neutron scattering. Although this method has already proven itself in studies of the phase distribution in steels, the literature only provides information on phases that differ greatly in structure, such as ferrite and austenite, austenite and martensite, or austenite and bainite. In this work, the possibilities of the method for visualizing the diffraction contrast between the ferrite and martensitic phases of steel with the same chemical composition and similar crystal structures were investigated.
