Given a ttt diagram of steel 1040. For each section determine the final steel structure. Mark the tracks on the graph. For your convenience, 2 identical graphs are attached below. Each section starts from a temperature of 800c: 1 Rapid cooling to 400c, staying for 100 seconds at this temperature and then rapid cooling to room temperature. 2. Rapid cooling to 600c, staying for 30 seconds at this temperature and then rapid cooling to room temperature. 3. Rapid cooling to 400c, staying for one second at this temperature and then rapid cooling to room temperature. 4. Rapid cooling to 700c Stay for 8 minutes at this temperature and then rapid cooling to room temperature.

Question
Given a ttt diagram of steel 1040. For each section determine the final
steel structure. Mark the tracks on the graph. For your convenience, 2
identical graphs are attached below. Each section starts from a
temperature of 800c:
1 Rapid cooling to 400c, staying for 100 seconds at this temperature
and then rapid cooling to room temperature.
2. Rapid cooling to 600c, staying for 30 seconds at this temperature
and then rapid cooling to room temperature.
3. Rapid cooling to 400c, staying for one second at this temperature
and then rapid cooling to room temperature.
4. Rapid cooling to 700c Stay for 8 minutes at this temperature and
then rapid cooling to room temperature.
