为了了解hydrogenation-decomposition-desorption-recombination过程中各向异性诱导的机理，用电子背散射和进动电子衍射研究了NdFeB合金在HDDR过程中的组织变化和晶体取向信息。复合Nd2Fe14B在NdH_2和α-Fe相界面处形核，并从复合反应开始就具有[0，0，1]取向织构。在分解阶段，铁颗粒沿1、1、3、3方向中的一种方向排列形成。这表明α-Fe极有可能诱导了复合Nd2Fe14B的织构发展。
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 NdH2and 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.
