摘要：

Neutron diffraction and mechanical spectroscopy studies were performed in Fe-Al-Cr, Fe-Al-Si and Fe-Si alloys. Results show that in ordered alloys independently of the type of order, D0(3) or B2, the mobility of dislocations and grain boundaries is markedly reduced. It is revealed through small values both of damping and of the strength of the amplitude dependent damping (S). Moreover, the behaviour of S as a function of temperature is a suitable tool for determining the order changes as a function of temperature.
