ANALYSIS OF DISLOCATION-STRUCTURE INHOMOGENEITY BY THE X-RAY-LINE WIDTH

X-ray scattering from polycrystals with nonuniformly deformed microstr uctural components has been studied in the kinematic approximation. Th e results obtained lend support to the possibility of using convention al techniques for determining the average dislocation density for case s where the dislocation density in the phase grains varies within one or two orders of magnitude. An experimental criterion for structural i nhomogeneity is suggested and quantitative evaluation of the parameter s of structural inhomogeneity is discussed.
