• A sharp maximum of permeabilities has been found in the narrow concentration range of about 12 percent aluminum in the slow cooled iron-aluminum alloys. It is found, however, that the permeabilities of this alloy are decreased and its coercive force is increased the reheat-treatment at temperatures between 400℃ and 650℃, followed slow cooling. For example, after reheating the alloy to 550℃ μ_m was decreased from 23,500 to 4,800, μ_0 from 1,600 to 1,000 and H_c was increased from 0.09 to 0.37 Oe. Since such a reheating effect was not found in the other concentration of iron-aluminum alloys, it is concluded that the phenomenon is due to something characteristic of 12 percent aluminum-iron alloy, that is the growth of a small quantity of precipitation or the short range order, which would result in an increase of internal strain.
