Abstract
The model of order-disorder phenomena in bcc binary alloys Fe-Al is st udied within the finite cluster approximation, which is superior of st andard mean-field theory. The phase diagrams of the system are investi gated. The thermal dependences of magnetic and structural order parame ters of the model are also given. Our study is done for selected ratio s V-ij/J(ij) of crystallographic interactions, V-ij, and magnetic exch ange J(ij). The results are compared with previous works.
