چکیده
The mechanical response of a bi-crystal model with 90° grain boundary under external compressive and tensile loading parallel to the plane normal was investigated molecular dynamics simulations. found migrate along two opposite directions upon straining, formation inter-connected coherent twin basal/prismatic boundary. atomic details such migration were unraveled, which indicated role interface dislocations. temperature effect also discussed.

Vacancy Generation During Grain Boundary Migration
We present a molecular dynamics simulation study of vacancy generation and emission from grain boundaries during curvature-driven grain boundary migration. The U-shaped half-loop bicrystal geometry is employed in order to maintain a constant driving force during boundary migration. Nonlinearities in plots of half-loop grain area versus time indicate the onset of non-steady-state behavior and va...
متن کاملAnalysis of the elastic strain energy driving force for grain boundary migration using phase field simulation
We investigate elastic energy-driven grain boundary migration in a strained copper bicrystal using an atomistically informed phase field model. In a bicrystal experiencing a uniform strain, the softer grain has a lower energy density and grows at the expense of the harder grain. In a bicrystal experiencing heterogeneous strain, the softer grain has a higher energy density, yet it still grows. O...
متن کاملAtom-by-atom observation of grain boundary migration in graphene.
Grain boundary (GB) migration in polycrystalline solids is a materials science manifestation of survival of the fittest, with adjacent grains competing to add atoms to their outer surfaces at each other's expense. This process is thermodynamically favored when it lowers the total GB area in the sample, thereby reducing the excess free energy contributed by the boundaries. In this picture, a cur...
متن کاملCooperative grain boundary sliding and migration process in nanocrystalline solids.
A new physical mechanism or mode of plastic deformation in nanocrystalline metals and ceramics is suggested and theoretically described. The mode represents the cooperative grain boundary (GB) sliding and stress-driven GB migration process. It is theoretically revealed that the new deformation mode is more energetically favorable than "pure" GB sliding and enhances the ductility of nanocrystall...
متن کاملUniaxial stress-driven coupled grain boundary motion in hexagonal close-packed metals: A molecular dynamics study
Stress-driven grain boundary (GB) migration has been evident as a dominant mechanism accounting for plastic deformation in crystalline solids. Using molecular dynamics (MD) simulations on a Ti bicrystal model, we show that a uniaxial stress-driven coupling is associated with the recently observed 90 GB reorientation in shock simulations and nanopillar compression measurements. This is not consi...
