Microstructures of Cr2B- and Fe2B-type borides, which were formed in the surface of SUS-304 by immersing into molten salt, were examined by means of electron diffraction and dark-field imaging techniques as well as high resolution electron microscopy. The orientation relationship between the Cr2B- and Fe2B-type structures was determined to be Cr2B (100)\varparallelFe2B (1\bar10) and Cr2B [001]\varparallelFe2B [111]. The Fe2B-type structure was found to have a twin with the [111] twin axis. The boundary of the twin lies macroscopically on the (1\bar10) plane, while micro-intergrowth of the two structures was observed near the boundary. Interpretation of the high resolution image of the intergrowth region indicated the existence of the following two kinds of defects; a twin of the Cr2B-type structure with the [011] twin axis and a (1\bar10) planar defect of the Fe2B-type structure. Geometrical consideration of the Cr2B- and the Fe2B-type structures indicates that both structures can be regarded as a layer-structure: they have almost the same component layers but have different stacking scheme. Atomic arrangements near the observed defects were interpreted from the geometrical similarity of the two structures.
