摘要：
In this work the behavior of edge 1/2 (111){110} and screw 1/2 (111){112} dislocations was investigated by the molecular dynamics method. The results of calculations show that the interatimic potential, which was used in this work, is able to properly describe the dislocation behavior. Two regimes of dislocation motion in molybdenum are shown to exist: Thermally-activated and viscous regimes. The obtained results for dislocation mobility was fitted using the dislocation mobility law. © 2017 Trans Tech Publications, Switzerland.
