Answer
For the hardening of steel, the microstructures that form at the various heat treating stages in part (a) are:
1. Austenite
2. Martensite
3. Tempered martensite
4. Tempered martensite
For precipitation hardening, the microstructures that form at the various heat treating stages in part (a) are:
1. Single phase
2. Single phase--supersaturated
3. Small plate-like particles of a new phase within a matrix of the original phase.
4. Small plate-like particles of a new phase within a matrix of the original phase.
