WebApr 8, 2024 · Crystallographic Analysis Using X-ray Diffraction Patterns. As a powerful tool to explore crystallographic information, XRD employing Cu K α radiation of wavelength 1.5406 Å was used for recording the diffraction patterns of the samples. Figure 1 represents the indexed XRD patterns of the samples in the 2θ range 10°–80° with a step size of … WebDue to the high concentration of defects in the grain contact area resulting from their crystallographic misalignment, diffusive transfer along the grain boundaries occurs much faster than in their bulk, where the defect concentration is much smaller (bulk diffusion), but slower than in the boundary between the solid … What are twin boundaries?
