    We study elastic anisotropy of a disordered Fe-Pd alloy under reversible elastic-like strains up to 4.3% by means of ultrasonic methods. The evolution of the full tetragonal tensor of elastic constants with a [001]-prestress ranging from 0 to 200 MPa is obtained, which enables an analysis of the change of the low frequency limit of the soft-phonon structure.
