10 points. What are the key differences between interstitial and substitutional diffusion? If you have Fe, name 3 elements that would diffuse interstitially and 3 that would diffuse substitutionally.

Answers

Diffusion mechanism (7 methods) 1. Interstitial diffusion (Na, Li) - fast processi Si Si - diffuses in interstitials. - doesInterstitial Diffusion Migration from one interstitial site to another (mostly for small atoms that can be interstitial impurSubstitution-diffusion vacancies and interstitials • applies to substitutional impurities • atoms exchange with vacancies Num

For Fe

interstitial diffusion - Arsenic, germanium, cadmium

Substitutional diffusion- Silicon, Nickel, Copper

Please dear thumpsup for the answer. Thank you.
