The magnetic properties and the phase Transformation of Tb1-xPrxFe1.96(x = 0 to 0.7) compounds were studied by means of vibrating sample magnetometer(VSM), X-ray diffraction(XRD) and SEM back-scattered electron (BSE). The result indicates that the saturation magnetization σs of compounds along an easy axis decreases with the addition of Pr contents, which reduces from 77.24 Am2 · kg−1 (x = 0) to 11.84 Am2·kg−1(x = 0.5) and then returns to 37.14 Am2·kg−1 (x = 0.7). The non-cubic phases appear when x exceeds 0.2, and the matrix of Tb1-xPrxFe1.96 compounds changes from (Tb, Pr)Fe2 phase with x = 0 to (Tb, Pr)Fe3 phase with x = 0.4, and at last to (Tb, Pr)2Fe17 phase in Tb0.3Pr0.7Fe1.96. Moreover, the structure of the compounds may become more complex with the increase of Pr content.
