| Abstract: | By using the first_principle augmented plane wave method and Chen's Theorem of 3_D lattice inversion,we got the atomic interaction potentical of Ni_Al_Ag and Ni_Al_Pd,and calculated phonon density and thermal properties of Ni_Al_Ag and Ni_Al_Pd metal chemical compounds.Furthermore,this paper analyzed the effect of the third metal on Ni 3Al lattice dynamic property and some thermal properties. |
