Abstract
An atomistic simulation of the deformation of ideal magnesium crystal along the $$[11\bar 20]$$ 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 0.1G (G is the shear modulus). The acting deformation modes are found to be prismatic slip of a dislocations and $$\{ 10\bar 13\} $$ 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 $$(\bar 3034)$$ plane.
