The microstructures of both as-cast and homogenized Nd-Fe-B ternary alloys have been studied. The stable phase regions existing in Nd-Fe-B ternary system at room temperature have been established by the microzone composition analysis and the phase identification. Based on the obtained results, an isothermal section of Nd-Fe-B ternary system at room temperature was drawn.

According to the experimental data of phase transition taken from DTA, metallography, SEM and microzone composition, two vertical sections of the ternary phase diagram (B=5.88 at.-%, Nd≤45.41 at.-% andNd_2Fe_(14)BNd_(1.1)Fe_4B_4 , B≤44.56 at.-%) have been drawn in detail. It is verified that the crystallization of both Nd_2Fe_(14)B and Nd_(1.1)Fe_4B_4 phase, during cooling from melt, would take peritectic reaction instead of solid-liquid congruent precipita- tion.
