Features and characteristics of high-speed deformation (nu = 3 x 10(8) s(-1)) of magnesium nanocrystals with "hard" and "soft" orientations were investigated numerically under uniaxial stress conditions using molecular dynamics simulations (MD). The evolution of dislocation density for two commonly utilized interatomic potentials is calculated. Deformation curves were constructed. Calculated strength and plastic properties of magnesium using different potentials are compared with each other. The influences of the type of interatomic potential on the calculated characteristics are discussed. The behavior of deformation curves for different interatomic interaction potentials is explained.
