Abstract :
Using anisotropic sintered bodies, the crystal orientation relationship between the parent Nd2Fe14B phase and the disproportionated mixture during the hydrogenation disproportionation desorption recombination (HDDR) treatment was investigated by using X-ray diffraction and transmission electron microscopy. It can be concluded that retaining the crystallographic orientation relationship such as <111>α-Fe and <111>(NdH2)//<001>(Nd2Fe14B), [110]α-Fe and [110](NdH2)//[100](Nd2Fe14B) during HDDR treatment is important for the inducement of anisotropy.
