What Does EGBD Stand For?

EGBD stands for Extrinsic Grain Boundary Dislocation

EGBD, or Extrinsic Grain Boundary Dislocation, refers to a type of dislocation that occurs at the boundary between two grains in a crystalline material. These dislocations arise from the misalignment of atomic planes at the grain boundary, leading to localized deformation and affecting the mechanical properties of the material. EGBDs play a critical role in influencing the strength, ductility, and overall performance of materials, particularly in polycrystalline metals and alloys. Their understanding is essential for advancements in materials science and engineering applications.
