See below the plot area for instructions
Melting Point A: Melting Point B:
AB Composition %B: Inversion Point %B: Inversion Temperature:
Eutectic %B: Eutectic Temperature: Melt Composition %B:

Instructions

Enter parameters in the boxes, or use the default values. To enter custom values:

• Inversion temperature must be lower than the melting points of either end member.
• Eutectic temperature must be below inversion temperature.
• Eutectic composition must be richer in B than compound AB.
• Inversion point composition must lie between AB and the eutectic composition.

An alert box will appear if any of these errors occur.

The Buttons

Draw Diagram

Self-explanatory. Draws the diagram specified by the input parameters. You can either run a simulation or redefine the diagram.

Evolve

Run a simulation with the specified melt composition.

Pause

Temporarily halt the simulation so you can study what's going on. Also gives numerical values for liquid and solid components. Press "OK" to resume. You can move the alert box if it blocks your view.

Reset

Resets the simulation to the beginning using the same diagram. You can redefine the melt composition or rerun the simulation again using the same composition. You can also use this to abort the simulation.

Clear Canvas

Erase everything

What's Happening?

Pauses the simulation and shows a brief explanation of what's going on at that stage of the simulation. Press "OK" to resume. You can move the alert box if it blocks your view.
