| A novel intermetallic compound, Nd3, Fe27.5, W1.5, that shows the monoclinic Nd3(Fe,Ti)29- type crystal structure (space group A2/m) has been obtained from powders homogeneously mixed and processed by arc melting. A notable reduction in the annealing time at 1100°C was obtained by using this procedure. From the Rietveld refinement of the powder X-ray diffractogram, the phase constitution and crystal structure were determined. The analysis shows that a 3:29 type compound is the majority phase (90 wt.%). It coexists with α-(Fe,W) (8 wt.%) and a 1:12 type phase (2 wt.%) as minority components. SEM and EDAX analyses were performed in order to characterize the microstructure. It was concluded that the 3:29 phase is the main component, in agreement with the results obtained by XRD and TMA. The Nd3Fe27.5W1.5 compund exhibits a Curie temperature of 124°C and a room temperature saturation magnetization of 96 emu/g (at Hmax = 16 kOe). | |
