This calculation type allows users to vary (or step in) one of the conditions specifying equilibrium. In this way, a series of equilibrium calculations is made where one of the conditions is changing, in steps, from one value to another. The results can be provided in a table or as a plot, as is the case for the example, which shows the volume-fraction of all stable phases present in a commercial Al-alloy, as a function of temperature.
A range of other properties can be plotted in a similar way, for instance composition of phases, heat capacity, density, and many more.
The plot shows a one-axis calculation of volume-fraction of stable phases as a function of temperature for Al-5.6Zn-2.5Mg-1.6Cu-0.2Si-0.15Mn (AA7075).
