Abstract

In this study, the magnetism and the elastic properties of Fe-Si alloys have been investigated using the all-electron FLAPW method based on the GGA. The local magnetic moment of Fe atoms decreases gradually. From the Pugh's relation and $C_P$, in the ordered $D0_3$ $Fe_3Si$, we predict that it presents intrinsic ductility.
