Nanostructured Fe_3Al intermetallic compounds were produced by using hydrogen arc plasma method(HP). The microstructures of the nano Fe_3Al were characterized by means of XRD, DSC-TG and TEM. The results shows that the intermetallic compounds have ordered B2 structure and the average particle of the as synthesized is about 45nm. The B2 structure changes to highly ordered DO3 structure after annealing in vaccum at 480℃. The temperature of phase transformation is 545.3℃.
