Abstract Scope The purpose of this is study is to investigate the effects of thermomagnetic processing on the established HDDR method of producing Nd2Fe14B anisotropic powders towards improving the energy product of bonded magnetic materials. Samples from a drop cast ingot were subjected to controlled H2 gas pressure in 0, 1, and 2 T applied magnetic fields to investigate the effect of H2 pressure on hydrogenation disproportionation (HD) in the presence of a magnetic field. This was followed by the desorption and recombination (DR) steps, under the previously stated magnetic fields. Between the HD and DR steps, samples were characterized using X-ray diffraction and magnetometry measurements to gauge improvements to phase fraction, magnetization, and magnetic coercivity caused by thermomagnetic processing. This work is supported by the Critical Materials Institute, an Energy Innovation Hub funded by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Advanced Manufacturing Office.
