Abstract:
Interactions of dislocations with one another and their interactions with impurities and precipitates determine the behavior of plastic deformation of crystalline materials. In this presentation, we will discuss recent advances in phase field modeling of dislocation network coarsening, solute segregation and phase transition at dislocations, and migration of dislocations through g channels in single crystal cuboidal g/g’ microstructures and g/g’ multilayer thin films of superalloys.
