摘要

An atomistic simulation of the deformation of ideal magnesium crystal along the [11 & Unknown;0] crystallographic axis has been performed. The evolution of structural defects under load at T = 300-350 K is considered in detail. It is established that the nucleation of dislocations in an ideal crystal occurs when the stress reaches a level of 0.1 G (G4s the shear modulus). The acting deformation modes are found to be prismatic slip of a dislocations and {10 & Unknown;3} twinning. The formation of dislocation networks and dislocation sites in the twinning plane is observed. Some reactions are proposed to describe the dislocation evolution in the (& Unknown;034) plane.
