Abstract
Furthermore, the deformation behaviors in adjacent TJs sharing two common grains are compared; local rotations, strain distributions, and activated slip systems within the same grain changes as it approaches a different TJ. Triple junctions consisted of three low-energy grain boundaries with special character yield lower triple line energy, and the tensile strain and slip activity may be reduced at such junctions. The understanding gained in my research will be important for developing predictive models for deformation in polycrystalline materials.
