We’re being asked to classify the given alloy as substitutional alloy, an interstitial alloy, or an intermetallic compound.
Recall the types of alloy:
• Substitutional Alloy – alloy where some of the most metal atoms have been replaced by other metal atoms that have a similar size
• Interstitial Alloy – allow where the empty spaces between the host metal atoms have been taken up by smaller metal/nonmetal atoms
• Intermetallic Compound – type of metallic alloy in which the compound exhibit a defined stoichiometry and ordered crystal structure
For each of the following alloy compositions indicate whether you would expect it to be a substitutional alloy, an interstitial alloy, or an intermetallic compound.
