WebA cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is an example of a cooling curve used in castings . The initial point of the graph is the starting ... Webcooling (low cooling rate). The cooling rate is maximum at the beginning of solidification and gradually decreases as the distance from heat extraction increases. T1 curve has the highest cooling rate by 14.569°C/s in Al–6wt.%Si cooling curve then it falls to 2.509 (T2), 2.256 (T3), and 2.287 (T4) °C/s accordingly (Figure 2b).
