Previous ab initio super-cell calculations of the magnetic properties of the ordered Fe_{1-x}Al_{x} alloy in the B2 structure are extended to include the disordered state of the alloy and completed with the calculations for ordered and disordered Fe_{1-x}Si_{x} alloys. The configurations of the Fe atoms in the anti-site (AS) positions of Fe-X super-cell with the antiferromagnetic order were found. The ground state of Fe_{1-x}Al_{x} with x≃ 0.3 shows the antiferromagnetic order of the Fe-AS magnetic moments. The concentration dependence of the equilibrium lattice parameter and magnetic moment of Fe_{1-x}X_{x} in the ordered and disordered state differ qualitatively.
