Abstract With the aid of 3-dimensional topological analysis methodology, relation-ships among phase regions on the isotherm section of the Nd-Fe-B phase diagram at 1000℃and those on vertical sections of the Pr-Fe-B phase diagram passing through Pr_2Fe_14B pointhave been re-discussed and modified.

Key words: Nd-Fe-B Pr-Fe-B ternary phase diagram topological analysis
