Substitutional

Substitutional and interstitial alloys Different atomic mechanisms of alloy formation, showing pure metal, substitutional, interstitial, and a combination of the two.

In some cases where the radius of the substitutional atom (ion) is substantially smaller than that of the atom (ion) it is replacing, its equilibrium position can be shifted away from the lattice site.

Phonon transport simulations indicate that substitutional defects such as nitrogen or boron will primarily lead to scattering of high-frequency optical phonons.

Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.

There are two different types of substitutional defects: Isovalent substitution and aliovalent substitution.

This is neither a vacant site nor is the atom on an interstitial site and it is called a substitutional defect.
