10 Questions
Alloys are generally preferred to pure metals in engineering work because of their inferior properties.
False
Alloys consist of a combination of two or more metal elements in the gaseous state.
False
The solubility of alloy elements in interstitial sites depends on the size of the gaps and the crystal structure.
True
Ordinary steels are alloys of iron and carbon.
True
The study of solid phases in alloys is important in understanding their properties.
True
