Generalized phonon densities of states (PDOS) for amorphous and alloys have been deduced from inelastic neutron scattering experiments. And the softening phenomena of the PDOS in the energy region below 17 meV have been observed for the amorphous Invar alloys. The anomalies in the dynamics of Invar alloys were discussed, and preliminary results show that the phonon softening of the amorphous Invar alloys may closely connected with the enhanced electron—phonon interaction in lnvar alloys.
