Papers by Keyword: Dislocation Mobility

Abstract: In this work the behaviour of edge 1/2<111>{110} and screw 1/2<111>{112} dislocations were investigated by the method of molecular dynamics. The results of calculations show that molecular dynamics with used interatimic potential are able to properly describe the dislocation behavior. Two regimes of dislocation movement in molybdenum are shown to exist: thermo-activated and viscous regimes. Obtained results of dislocation mobility was fitted using the dislocation mobility law.
