Analysis of dislocation structure inhomogeneity by the X-ray line width

X-ray scattering from polycrystals with nonuniformly deformed microstructural components has been studied in the kinematic approximation. The results obtained lend support to the possibility of using conventional techniques for determining the average dislocation density for cases where the dislocation density in the phase grains varies within one or two orders of magnitude. An experimental criterion for structural inhomogeneity is suggested and quantitative evaluation of the parameters of structural inhomogeneity is discussed
