Abstract
The ribbons of Pr1.4Fe10.5Mo1.5 and Nd1.4Fe10.5V1.5 have been prepared by melt-spinning process. The ribbons are determined to 1:7 phase with TbCu7-type sturcture by TEM and XRD. DTA and XRD show that the temperature of Pr(Fe, Mo)7 being transformed into 1:12 Phase, Pr(Fe, Mo)12, is 674. 78℃; α-Fe being decomposed from Pr(Fe,Mo)12 is 819.87℃; the temperature of Nd(Fe,V)7 being transformed into 1:12 phase, Nd (Fe,V)12, is 784.17℃, while in the temperature range from room temperature to 1300℃, there is no α-Fe being observed.
