Abstract

The propagation and fracture process of void in magnesium single crystal at the nanoscale have been investigated using molecular dynamics simulation and embedded atom method at different temperature. The results show that the temperature has a significant effect on the potential energy and yield strength of the system, the system potential energy and yield strain increase with the increase of temperature. When the temperature is 100K, the plastic deformation mode of the specimen belong to mainly dislocation movement. And the plastic deformation belong to mainly dislocation movement and a small amount of base plane slip at 300K. Furthermore, the plastic deformation is mainly non basal surface slip at 500K.
