Abstract

In the present paper, to investigate the. phonon frequencies of face-centered-cubic (f.c.c.) Fe-1 8%Cr-1 Oo/oMn-16%Ni and
Fe-18%Cr-12%Ni-2%Mo a1loys it has been used an empirical many-body potential (MBP) developed by Akgün and Uğur,
recently. The parametcrs defıning the MBP f.c.c. alloys m ay be computed by following a procedure deseri bed. The radial

Keywords

many-body potential , phonon frequencies , radial force constant , tangential force constants
