| Abstract: | Comparison is made between experimental phonon dispersion curves for one crystal of composition Fe-22.5% Al in the disordered state (BCC), and two crystals of composition Fe-25% Al, one with B2 order and the other with DO3 order. The different states of order represent different arrangements of the iron and aluminium atoms on the sites of BCC lattice. |
