1. Dislocation is fall under categories of "line defect'.

• correct

• incorrect

An extra atom is present in the void between atoms is called "vacancy".

• correct

• incorrect

Less distortion is created under self-interstitial defect.

• correct

Burgers vector is perpendicular to dislocation line in "edge dislocation".

• correct

• incorrect

Dislocation has less influence to material properties.

• correct

• incorrect

Twist boundary is formed by edge dislocation aligning up in a line.

• correct

• incorrect

Twin boundary is formed either by stress or annealing.

• correct

• incorrect

Diffusion is a process of mass transfer by movement of atoms from lower chemical potential to higher chemical potential.

• correct

• incorrect

Vacancy diffusion is more rapid than interstitial diffusion.
