1. Hour 1A map of iron and carbon
2. Hour 2Austenite is the parent
3. Hour 3Slow. True. Fast.
4. Hour 4The HAZ already saw this

CheckPoint ferrite, austenite, cementite, pearlite on the wall map. Draw a heat and a cool. Say slow, true, or fast. Do not invent degrees. Link the HAZ. A change is not a melt. Solid metal can rewrite its rooms. Oil quench is a fire risk. The paper owns the cool.
