Question

Why strengnthening by interstitial solid solution is more than substitutional

Answer 1

$\huge\mathfrak\pink{Hello,}$

$\huge\underline{Answer}$

Substitutional solid solution strengthening occurs when the solute atom is large enough that it can replace solvent atoms in their lattice positions. ... The atoms crowd into the interstitial sites, causing the bonds of the solvent atoms to compress and thus deform.
