including a discussion of how heat and carbon content impact a steel's microstructure. This class also describes common heat treating methods, such as annealing, quenching, normalizing, and tempering.

The micrographs below show the effect of annealing at different temperatures on a sample of Fe - 0.7 wt % C steel in which martensite has been formed by quenching. Because of the low carbon content ...

An example of these heat treatment processes is covered in one study that investigated the microstructural changes in AISI ...
