Structural, magnetic and thermal characterization of Fe 50 Se 50 powders obtained by mechanical alloying

In this paper, Fe50Se50 alloy powders were synthesized from pure elemental powder by mechanical allowing. The structure, microstructure, morphology, chemical composition and thermal behavior at a function of milling times (0-39 h) were investigated by X-ray diffraction (XRD), scanning electron micro...
