With decarburization, the decarburized layer will be free of carbide phases. Carbon steel will be ______.
A) Annealed
B) Quenched
C) Pure iron
D) None of the above

Question

Quizplus · Accepted Answer

Decarburization is the process of removing carbon from the surface of a steel. This can be done by heating the steel in an oxygen-rich atmosphere, which causes the carbon to react with the oxygen to form carbon dioxide gas. The decarburized layer will be free of carbide phases, which are hard and brittle compounds that can make the steel more difficult to work with. Annealing is a process of heating and cooling steel to soften it, quenching is a process of rapidly cooling steel to harden it, and pure iron is a type of steel that does not contain any carbon.
