Answer
With regard to the total heat treatment procedure, the steps for the hardening of steel are as follows:
1. Austenitize above the upper critical temperature.
2. Quench to a relatively low temperature.
3. Temper at a temperature below the eutectoid.
4. Cool to room temperature.
With regard to precipitation hardening, the steps are as follows:
1. Solution heat treat by heating into the solid solution phase region.
2. Quench to a relatively low temperature.
3. Precipitation harden by heating to a temperature that is within the solid two-phase region.
4. Cool to room temperature.
