N2 - Microstructural changes and crystallographic orientation information in the hydrogenation-decomposition-desorption-recombination (HDDR) process of Nd-Fe-B alloy were investigated using electron backscatter diffraction (EBSD) and precession electron diffraction (PED) in order to understand the mechanism of anisotropy inducement in the HDDR process. Recombined Nd2Fe14B grains were found to nucleate at the interfaces between NdH2 and α-Fe grains and to have a [0 0 1]-oriented texture from the beginning of the recombination reaction. The Fe grains form with alignment of one of the 〈1 1 3〉 directions at decomposed stage. This suggests that α-Fe most likely induces texture development of recombined Nd2Fe14B.
