The density and ferromagnetic properties in annealed as well as in quenched states of iron-aluminium alloys containing less than 17%Al have been measured. Densities of alloys containing more than 10%Al decrease by quenching from 700℃, the observed relative changes being in good agreement with values calculated from the data for changes in lattice parameter obtained by Bradley and Jay. The saturation magnetization in alloys containing 10 to 12%Al increases, while that in alloys containing more than 13% Al decrease by quenching, indicating that the Fe_3Al→FeAl transition may accompany a fall in Curie temperature. The magnetization in alloys containing some 17%Al is low, and never attain to saturation even at high fields. It is also shown that the magnetocrystalline anisotropy constant of iron decreases by the addition of aluminium and changes its sign near the Fe_3Al composition.
