The wettability between Nd 2Fe 14B and Nd-rich phases has been investigated through the sessile drop method. The compositions of prepared Nd-rich ingots were Nd 72.0Fe 26.1B 1.9 (ternary) and Nd 72Fe 22.4Cu 3.7B 1.9 (Cu-added). Nd-rich ingots were cut and put on a polished Nd 2Fe 14B plate and heated in a furnace. Contact angles between Nd 2Fe 14B plate and Nd-rich ingots were measured as a parameter of wettability under controlled temperature. For the Cu added sample, both contact angles in all temperature range and temperatures when contact angle starts to change were lower than those for ternary sample. These results indicate Cu substitution yields improvement of wettability. DTA measurements for two Nd-rich ingots reveal that their contact angles starts to change at lower temperature than their melting points It is considered that those phenomena are derived from the existence of Nd 2Fe 14B/Nd-rich interface.
