dc.description.abstract | We investigated the changes in microstructure and magnetic properties of Nd-Fe-B magnets as a function of Cu content (Cu addition in the range of 0.2-0.5 at. %). We have focused on the phase-transformation temperature of the Nd-rich phases in dependence of the Cu content. The coercivity of the magnets decreased (from 28.7 kOe to 27.1 kOe) on increasing Cu content under identical post-sintering annealing (PSA) conditions. The Cu-enriched C-Nd2O3 triple junction phase (TJP) and grain boundary phase (GBP) were observed in the 0.2 at.% Cu-containing magnet. However, in the 0.5 at.% Cu-containing magnet, the Cu-enriched TJP and GBP appeared in the form of the h-Nd2O3 phase that could be transformed into the C-Nd2O3 phase by a modified 1st-PSA temperature. The coercivity of the 0.5 at.% Cu-containing magnet was noticeably enhanced (from 27.1 kOe to 29.4 kOe). | - |
