Question
Substitutional alloy and interstitial alloys are types of alloys.
- True
- False
Hint:
Alloys can be one of two general types
The correct answer is 'True'.
Alloys can be one of two general types
- Substitutional Alloys: Substitutional alloys are metal alloys formed by substituting one metal atom for another metal atom of similar size.
- Interstitial Alloys: IInterstitial alloys are metal alloys formed by inserting smaller atoms into holes of the metal lattice.
- Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms
