In a crystal, there exist a point defect of the interstitial atom. If solute atom is larger than the solvent atom, then which is true for the edge dislocation?

Correct Answer: Compression side of edge dislocation will repeal and will be attracted to the tension side
If the solute atom is larger than the solvent, it will create a local region of compression. So the tension side of dislocation will attract at this region, and compression side will repel from this region.
