Abstract: Using the Modified Analytic Embedded Atom Method(MAEAM),the phonon spectra and lattice specific heat of bcc metals(Cr,Fe,W,Mo,Ta,V,Nb) are calculated.The obtained results are in good agreement with the experimental data.It is improved greatly as compared with the calculated results by the Johnson model.And the influence on EAM model of the characteristics of bonding orientation of these transition bcc metals is discussed.
Key words: MAEAM, bec metals, phonon spectra, specific heat
