Abstract

In the present work, new possibilities of the X-ray diffraction for investigations of the phase composition, size, shape and volume fraction of particles in ultrafine-grained (UFG) martensitic steel and the Cu-Cr-Zr alloy have been demonstrated. For the first time, the method of X-ray diffraction in the transmission mode was used to identify particles with a volume fraction of less than one percent in the UFG materials studied. The small-angle X-ray scattering method was used to estimate the size and shape of dispersed particles. Specific features of the UFG structure determined by the X-ray diffraction are compared with the results of TEM studies.
