- In this paper the investigations of the ordering, microstructure and magnetomechanical properties of the $Fe_{80}Ga_{20}$ alloy and its composites are presented. The composites consisted of the Fe-Ga particles with a size distribution in the range between 20 and 50 μm. These particles were produced by blade-milling of arc-melted alloy. After milling the powders were annealed at 723 K for 2.5, 7.5, and 12.5 h. The epoxy-bonded composites in rectangular shape were made from the as-cast as well as from the annealed powders. The Mössbauer spectroscopy studies revealed that the as-cast alloy is completely disordered. After annealing at 723 K the long range atomic order appeared. It was stated that the best magnetoelastic properties were exhibited by composites made from ferromagnetic particles obtained from the as-cast alloy. The measured saturation magnetostriction was $λ_s = 70× 10^{-6}$ for the bulk alloy and $λ_s=100× 10^{-6}$ for composite.
