Lever Rule Ternary Phase Diagram
The simulation is available at. It is really invoking the conservation of mass and can be proved mathematically as shown below the diagram.

Ternary systems are those having three components.
Lever rule ternary phase diagram. It is not pos sible to describe the composition of a ternary alloy with a single number. If at the given pressure and temperature the overall composition of the system z a is found within these values x a z a y a in the t x diagram or y a z a x a in the p x diagram the system will be in a two phase condition and the vapor fraction α g and liquid fraction α l can be determined by the lever rule. Uses a simulation to show how ternary phase diagrams are interpreted.
The lever rule if an alloy consists of more than one phase the amount of each phase present can be found by applying the lever rule to the phase diagram. How to read ternary phase diagram. This is for a single phase three component system.
The composition of the alloy is represented by the fulcrum and the compositions of the two phases by the ends of a bar. Ternary phase diagrams wel e to brock determining position on ternary diagrams the position of each point in terms of the end member ponents can be read directly from the diagram reading a ternary diagram ternary plotting program power power point presentation animating how to read a ternary diagram and applying it to clastic rock classification and. Lever rule the lever rule is a rule used to determine the mole fraction x i or the mass fraction w i of each phase of a binary equilibrium phase diagram.
At first sight the lever rule can appear confusing. Thus suppose a ternary mixture stream the composition of which is represented by point a on the phase diagram below left enters a settler below center which disengages the two equilibrium liquids from each other into streams b and c. The ratio of the two phases present can be found by using the lever rule.
Ternary phase diagrams represent the phase behavior of mixtures containing three components in a triangular diagram. Phase diagrams are graphical representations of the liquid vapor and solid phases that co exist at various ranges of temperature and pressure within a reservoir. It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.
Lever rule cannot be used here it can be assumed that moving closer to an spb line will likely increase the amount of the phase while moving closer. The lever rule also applies to these phase diagrams. Now that we know the compositions of the two phases we need to find how much of each phase exists at the given temperature.
