Abstract

In this paper the investigations of the ordering, microstructure and magnetomechanical properties of the Fe80Ga20 alloy and its composites are presented. The composites consisted of the Fe-Ga particles with a size distribution in the range between 20 to 50 μm. These particles were produced by blade milling of arc-melted alloy. After milling the powders were annealed at 723K for 2.5, 7.5 and 12.5 hours. The epoxy-bonded composites in rectangular shape were made from the as-cast as well as from the annealed powders. 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 λs= 70 x 10-6 for the bulk alloy and λs=100 x 10-6 for composite.
