Metastable Crystalline and Amorphous Fe–V Alloys Produced by Vapor Quenching

抄録

Fe_1−xV_x alloys obtained by vapor quenching have been investigated by X-ray diffraction, magnetization and Mössbauer effect measurements. The single bcc phase appears for 0≤x≤0.3 and 0.6<x≤1.0, while the single amorphous phase for 0.45≤x≤0.5, where the σ phase is stable in the equilibrium phase diagram. Since the bcc and amorphous phases are magnetically distinct, the volume fraction of the paramagnetic amorphous phase was estimated. The Mössbauer spectra indicate that the amorphous alloys have a short range atomic arrangement similar to that of the σ phase.
