Faceted core–shell interfaces with an abrupt change in Dy concentration suggest the Dy-rich shells are formed by the solidification of the liquid phase during cooling from the GBDP temperature. The Nd-rich phases are almost free from Dy, and their quantity near the surface of a bulk sample is much higher than that in the center, indicating that a higher fraction of a liquid phase exists near the surface during processing at 900 °C. These microstructural features are explained on the basis of the phase equilibrium between Nd and Nd 2 Fe 14 B at the processing temperature and subsequent cooling. Based on the results, we discuss the coercivity enhancement by the GBDP using Dy vapor."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319963683072","@type":"Researcher","foaf:name":[{"@value":"S.
