Problem

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.

Fe0.97Si0.03

Solution

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Substitutional Alloy – alloy where some of the most metal atoms have been replaced by other metal atoms that have a similar size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
