Abstract Scope |
Thermo-Magnetic Processing (TMP) - HDDR (hydrogenation, disproportionation, desorption, recombination), or HDDR within an applied magnetic field, can produce anisotropic Nd2Fe14B powders with improved magnetic properties using drop-cast Nd-Fe-B alloy as feedstock. We investigate the effectiveness of TMP-HDDR in 0, 0.5, and 1 Tesla fields and a controlled H2 environment on drop-cast and commercially-attained sintered Nd2Fe14B magnets, and compare the resulting properties. Samples were characterized using X-ray diffraction, magnetometry, and electron microscopy to differentiate between TMP-HDDR on commercial samples versus those synthesized in the lab.
