Question

introduction of substitutional solid solution and interstitial solid solution
​

Answer 1

Answer:

Interstitial solid solutions form when the solute atom is small enough (radii up to 57% the radii of the parent atoms) to fit at interstitial sites between the solvent atoms. The atoms crowd into the interstitial sites, causing the bonds of the solvent atoms to compress and thus deform.

Answer 2

Answer:

Depending on the size of the alloying element, a substitutional solid solution or an interstitial solid solution can form. ... Substitutional solid solution strengthening occurs when the solute atom is large enough that it can replace solvent atoms in their lattice positions.
