The disordered solid solution Al was obtained for Fe_(25)Al_(65)Ni_(10) mixture powder. The mechanical alloying of Fe_(0.25)Al_(0.75-x)Ni_x(x=0.05,0.175,0.25) mixture powders result in intermetallic compounds. The results of mechanical alloyed_(1-x)Ni_x (x=0.4,0.6) and (FeAl_3)_(1-x)Ni_x(x=0.1,0.3) mixture powders indicate that the ratio of iron and aluminum determines the formation of intermetallic compounds. The FeNi intermetallic compound, cerium oxide and one unidentified phase were obtained by mechanical alloying FeCeNi_3 and Ce_2 mixture powders.
