Abstract
High-resolution neutron diffraction is employed to determine the main structural parameters and microstrain levels of several austenitic 16Cr-15Ni-3Mo-1Ti steel samples subjected to different degrees of cold plastic deformation and estimate the dislocation densities thereof. It is demonstrated that the anisotropic diffraction peak broadening observed in the neutron experiment is caused by variations in the dislocation-contrast factor and can be satisfactorily described with the help of the used model. Comparative analysis of the results obtained by neutron diffraction and transmission electron microscopy is performed.
