What does IGBD mean in UNCLASSIFIED
IGBD stands for Intrinsic Grain Boundary Dislocation. It refers to a dislocation that forms at the boundary between two grains in a crystalline material. Dislocations are line defects in crystals that can disrupt the regular arrangement of atoms.

IGBD Formation
IGBDs form when two grains with different orientations meet. The misorientation between the grains creates a strain field that can lead to the formation of dislocations. These dislocations are located at the grain boundary and can extend into the adjacent grains.
IGBD Properties
- Types: IGBDs can be classified as either edge dislocations or screw dislocations, depending on their Burgers vector.
- Orientation: The orientation of an IGBD is determined by the misorientation between the grains it separates.
- Strength: The strength of an IGBD depends on the magnitude of the misorientation and the type of dislocation.
- Mobility: IGBDs can move or glide under the influence of stress, which can affect the mechanical properties of the material.
IGBD Effects
- Strength: IGBDs can weaken grain boundaries, making the material more susceptible to fracture.
- Diffusion: IGBDs can act as fast diffusion paths for atoms and ions, facilitating grain boundary diffusion.
- Creep: IGBDs can contribute to creep deformation under stress by providing pathways for dislocation glide.
- Grain Growth: IGBDs can inhibit grain growth by pinning grain boundaries and preventing them from moving.
Final Words: IGBDs are line defects that form at grain boundaries in crystalline materials. They play a significant role in determining the mechanical, electrical, and chemical properties of the material. Understanding the behavior of IGBDs is crucial for optimizing the performance of materials in various applications.
