摘要: Abstract The phase relations in the pseudo-binary Nd2Fe14B–Pr2Fe14B system were investigated and constructed by means of X-ray powder diffraction (XRD), differential scanning calorimetry (DSC) electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). results revealed that similar to end-members form a continuous solid solutions, all intermediate (Nd1−xPrx)2Fe14B samples belong tetragonal Nd2Fe14B-type structure (space group P42/mnm). lattice parameter almost remains same, c unit-cell volume V increase linearly an Pr concentration. Based on DTA measurements examinations, tentative diagram isopleth has been constructed.
