We evaluated the correlation between the computational design and the elongation as well as the dislocation mobility on a variety of HEA alloys based on external materials databases and developed the EAM potentials for a selected number of multi-component systems. The source of external materials database primarily is used on the reference from Data in Brief (2018, 2664-2678) by S.Gorsse, M.H.Nguyen, O.N.Senkov, and D.B.Miracle, combined with the secondary references to obtain the stress-strain curves (if available). We then sampled a number of multi composition systems that represent various degree of elongation and parameterized the necessary EAM interatomic potentials to observe the effect of the compositional variation toward the dislocation mobilities. The roles of the local chemical bonding within the structures are also discussed.
