Interatomic Interaction and Vacancy Mobility in FCC Metals

Russian Metallurgy (Metally). 2013. No. 7. P. 522-527.
Iskakov B., Baigisova K.

A simple set of equations is derived to determine the Morse interatomic interaction potential parameters without any assumptions. These parameters are calculated for a model fcc crystal represented as 30 configuration spheres made of 1060 atoms surrounding a central atom. The dependences of these parameters on the number of surrounding atoms are obtained. The found parameters are used to calculate the energies of vacancy migration in 11 fcc metals using the proposed configuration sphere method.
