By combining a scanning-type white X-ray micro-diffraction system with high-energy synchrotron X-rays, images were obtained non-destructively for visualizing grain boundaries and grains in stainless steel by simple data processing. The images were comparable to those obtained by electron back scattering pattern technique. It was shown that the new method could be applied to bulky plate sample as thick as 300 µm containing grains with size of 100 µm.
