Molecular dynamics simulation is applied to investigate the microstructure evolution of magnesium single crystals under c-axis extension at different temperatures.At low temperatures,both {10ī2} and {10īl} twins are observed.At elevated temperatures,{10ī1} twining decreases quickly with increasing temperature,while the amount of {10ī2} twins increases.The {10ī2} twin.is found to be the main deformation mechanism under the c-axis tension in the magnesium single crystal.Meanwhile,shear bands are also observed during deformation.When the temperature is beyond 500 K,the non-basal plane slip due to the thermal.activation is found.The stress-strain curves related with deformation behavior at atomistic scale are presented.
