The method for obtaining anisotropic hard magnetic Nd2Fe14B powders by the process Hydrogenation–Disproportionation–Desorption–Recombination (HDDR process) Nd–Fe–B type alloy with high content of Nd has been considered in this study. Two different types of HDDR (dynamic and solid) process have been studied. The dependence of magnetic hysteresis properties on hydrogen pressure and its pumping rate at the disproportionation stage is shown. It is found that a solid HDDR makes it possible to obtain powders with higher coercivity and the hysteresis loop rectangularity than a dynamic HDDR.
