The interplay between structure evolution and magnetic properties of nanocrystalline Fe67W33 alloys prepared by mechanical alloying was investigated by calorimetric, structural, magnetization and Moessbauer studies. Two solid solutions of ferromagnetic bcc Fe(W) and paramagnetic bcc W(Fe) were detected. The grain sizes became about 10 nm after 115 hours of milling and the lattice constants, 0.29261 nm for the Fe(W) and 0.31590 nm for the W(Fe) phase, respectively. Furthermore the effective magnetic moments were reduced to 0.5 μB after the 150 hours of milling. The strong ferromagnetic interaction is confirmed by Curie temperatures exceeding 1000 K.
