| Abstract Scope |
It has been discovered that it is possible to create High Entropy Alloys (HEAs) that possess attractive properties for engineering applications. However, the exact mechanism behind why these HEAs exhibit such properties remains relatively elusive. As part of a multi-scale approach, Discrete Dislocation Dynamics (DDD) simulation is gaining traction in mesoscale modeling. A dislocation modeled as an elastic line evolving in a quenched noise has already been utilized to study the influence of solid solution on glide. In this study, we introduce a novel way to investigate dislocation glide under the effect of stacking faults in alloys. The characteristic length of the correlation sampled from molecular dynamics is utilized to sample correlated quenched noise. Then, elastic partial dislocations with static stacking faults are evolved through time. This study lays the foundation for investigating partial dislocation motion in mesoscale simulations. |
