Digging Into Phase Diagrams Cooling Curves Physical Chemistry The cooling curve method is one of the oldest and simplest methods to determine phase diagrams and phase transition temperatures. this is achieved by recording temperature (t) of a material versus time as it cools from its molten state through solidification (at constant pressure). whenever a phase change takes place in a metal or alloy, the. A cooling curve for a sample that begins at the temperature and composition given by point a is shown in figure 8.10.1b 8.10. 1 b. figure 8.10.1 8.10. 1: (a) cooling of a two component system from liquid to solid. (b) cooresponding cooling curve for this process. as the sample cools from point a, the temperature will decrease at a rate.

Digging Into Phase Diagrams Cooling Curves Physical Chemistry The cooling curve phase diagram is a graphical representation of this solidification process, which helps us understand the behavior of different substances during solidification. the cooling curve phase diagram consists of two axes: temperature and time. it shows the temperature of the substance on the y axis and the time on the x axis. The curve bc in figure 11.5.2 is the plot of vapor pressure versus temperature as described in the previous section of this chapter. this “liquid vapor” curve separates the liquid and gaseous regions of the phase diagram and provides the boiling point for water at any pressure. for example, at 1 atm, the boiling point is 100 °c. 10.4 phase diagrams chemistry 2e. By removing the time axis from the curves and replacing it with composition, the cooling curves indicate the temperatures of the solidus and liquidus for a given composition. this allows the solidus and liquidus to be plotted to produce the phase diagram: this page titled 12.5: interpretation of cooling curves is shared under a cc by nc sa.
