Figure 3 shows the strong effect of the time to cool from 800 to 500°C after ,welding, (ΔT8/5) on the properties in the ,weld,'s ,heat,-affected zone (HAZ). While the ,carbon, content controls the plateau hardness of the martensite at very short cooling time, the CE determines when martensite forms during cooling.
