Web26 okt. 2024 · Where does activation energy occur in substitutional diffusion? The diffusing atoms jumps from one interstitial to neighboring interstitial site in executing a unit step. The neighbouring site is usually vacant in dilute solutions. The activation energy is simply the energy barrier along the path from one interstitial to next. http://www.minaprem.com/materials-science/defects/point-defect-imperfections-in-solids-materials-science/

WebSubstitutional alloys have "solute" atoms that replace "solvent" atoms in a lattice, but interstitial alloys have "solute" atoms that are in between the "solvent" atoms in a lattice. True The atomic radii of the atoms in a substitutional alloy are similar to each other, but in an interstitial alloy, the interstitial atoms are a lot smaller than the host lattice atoms. Web1 feb. 2024 · The defects in the crystal due to the irregularities in the arrangement of atoms or ions are called atomic imperfections. They are due to missing or misplaced ions. Such defects are referred as point defects.
