Question

Difference between in interstitial phase and substitutional solid solution

Answer 1

Answer:

Substitutional solid solution

This type of reaction occurs when the solute atom is larger than the solvent atom. The solute atom occupies an interstitial position in the crystal latex. The solute atom replaces the solvent atom in the crystal latex. An example of interstitial solid solution is carbon in iron.

Answer 2

Answer:

Substitutional solid solution strengthening occurs when the solute atom is large enough that it can replace solvent atoms in their lattice positions. ... Interstitial solid solutions form when the solute atom is small enough to fit at interstitial sites between the solvent atoms.
