- 1805 Discrete Dislocation Dynamics Simulation of Dislocation Cutting into Gamma-Prime Phase Based on APB Energy
抄録
We proposed a back force model for simulating dislocations cutting into a γ' precipitate, from the physical viewpoint of work for making or recovering an anti-phase boundary (APB). The model is encoded in the 3D discrete dislocation dynamics (DDD) code and applied to the cutting behavior of dislocations at a γ/γ' interface covered by an inter facial dislocation network. The first dislocation generated from Frand-Read source piles up at the interface not by the stress field of the network but by the back force against making an APB. The second dislocation, however, stands off from the interface by the stress field of the first dislocation and the dislocation network. The finer mesh of the network, the further the second dislocation piles up. These two dislocations cut into the precipitate forming a superdislocation under the force from follow-on dislocations.
