Which of the following is TRUE concerning interstitial alloys?
A) The metal takes on the properties of the foreign atoms once they are present.
B) Small atoms fit in between the metal atoms in the crystal structure.

D) The foreign atoms present weaken the metallic structure.
E) None of the above is true.

Question

Quizplus · Accepted Answer

Interstitial alloys involve the insertion of small atoms, usually non-metallic, in between the metal atoms in the crystal lattice. This can lead to changes in the properties of the metal, but the metal does not take on the properties of the foreign atoms. Brass is not an interstitial alloy, but a substitutional alloy. The foreign atoms in interstitial alloys do not necessarily weaken the metallic structure, and in some cases can actually strengthen it.
