Hot stage in transmission electron microscope has been used to study the structure and stability of Nd-rich phase in NdFeB magnet. The present observation shows that the so-called complex cubic phase is in fact the prototype of Mn2O3 (space group Ia 3) with lattice parameter of a 1⁄4 1:08nm: The Nd-rich phase with P 3m1 structure (h-Nd2O3) was first observed to be transformed from the BCC phase after in situ heating over 400 1C. The orientation relationship between these two structures… CONTINUE READING
