PHASE DIAGRAM OF Nd-Fe-B TERNARY SYSTEM——I.Isothermal Section at Room Temperature

The microstructures of both as-cast and homogenized Nd-Fe-B ternary alloys have beenstudied. The stable phase regions existing in Nd-Fe-B ternary system at room temperaturehave 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 roomtemperature was drawn.
