Abstract
Multi-phase microstructures were observed in the psuedo-quaternary phase fi eld of the 2-14-1 magnet materials Nd2Fe14B, Nd2Co14B, Dy2Fe14B, and Dy2Co1 4B. At equilibrium, (Nd1-yDyy)(2)(Fe1-xCox)(14)B had heretofore been widely assumed to be single phase where 1 > x > 0 and 1 > y > 0. In this study, t hree-phase microstructures were observed in (Nd1-yDyy)(2)(Fe1-xCox)(14)B wh en x > 0.3 and y > 0.5. The Curie temperatures and peritectic decomposition temperatures for Nd-2(Fe1-xCox)(14)B are reported for several values of x in the range 1 > x > 0. (C) 2001 Published by Elsevier Science B,V.
