Abstract
An experimental study of the liquidus projection in a phase diagram of the Nd-Fe-B ternary system has been carried out. In the Nd-poor region, it is found that two phases, Fe2B and Nd2Fe7B6(T2), coexist with the liquid. Two monovariant curves, L\rightleftharpoonsFe+Fe2B and L\rightleftharpoonsFe2B+T2, join and form the transition reaction, L+Fe2B\rightleftharpoonsT2+Fe. The end point of the liquid in the Nd-poor regions is the ternary eutectic point, L\rightleftharpoonsFe+Nd2Fe14B(T1)+T2. The T2 and Nd2FeB3(T3) phases simultaneously solidify from the liquid. In the Nd rich region. T1 phase, T2 phase and (Nd) solid solution solidify from the liquid at the end point of the liquid.Keywords
