Ternary Phase Diagram Examples

This example calculates an isothermal section using the Ternary module. The FEDEMO database is used and included with your installation.

These commands are used:

• AMEND_PHASE_DESCRIPTION
• ADD_LABEL_TEXT
• PLOT_DIAGRAM
• SET_DIAGRAM_AXIS; SET_DIAGRAM_TYPE; and SET_AXIS_TYPE
• SET_REFERENCE_STATE
• CHANGE_STATUS
• SET_SCALING_STATUS

This example calculates a vertical section in the Al-Cu-Si system and of a vertical section from Al to 10% Cu₂Si. The ALDEMO database is used and included with your installation.

This example calculates the heat and heat capacity variations during solidification of an Al-Mg-Si alloy. The ALDEMO database is used and included with your installation.

These commands are of note and used in this example:

• LIST_SYSTEM
• LIST_CONDITIONS
• SET_AXIS_TEXT_STATUS

This example calculates the pseudo-binary system CaO-SiO₂ using the OXDEMO database, which is included with your installation.

The oxide demo (OXDEMO) database can be used both for pseudo-binary systems like the one in this case, CaO-SiO₂, or for full ternary systems like Ca-Fe-O.

For a more advanced example in Graphical Mode using the TCS Metal Oxide Solutions Database (TCOX), see T_17: Al2O3-MgO Phase Diagram.

These commands are of note and used in this example:

• LIST_SYSTEM
• REJECT and RESTORE
• AMEND_PHASE_DESCRIPTION
• LIST_STATUS
• DEFINE_COMPONENTS
• SET_CONDITION
• COMPUTE_EQUILIBRIUM and LIST_EQUILIBRIUM

• Part A. Step-by-step calculation using the POLY3 module.
• Part B. Using the TERNARY module, you can get the information on invariant reactions, such as temperature and compositions.

The database used with this example is included with the file named tcex19_cost2.TDB. It is in the same folder as this example.

These commands are of note and used in these examples:

• DEFINE_SYSTEM
• GET_DATA
• AMEND_PHASE_DESCRIPTION
• SET_CONDITION and LIST_CONDITIONS
• ADVANCED_OPTIONS
• SAVE_WORKSPACES and READ_WORKSPACES
• APPEND_EXPERIMENTAL_DATA
• MAKE_EXPERIMENTAL_DATAFILE

This example calculates a ternary isotherm in Fe-Cr-Ni with a user-defined database included with the example in the file named tcex21.TDB.

These commands are of note and used in this example:

• DEFINE_SYSTEM
• GET_DATA
• SET_CONDITION
• SET_DIAGRAM_TYPE

This example is a benchmark calculation of an isopleth in the Fe-Cr-C system. The FEDEMO database is used and included with your installation.

This example shows how to use command lines to enter and calculate an isothermal section using the POLY3 module. The FEDEMO database is used and included with your installation.

This uses the TCFE database. A license is required to run the example.

This example uses an Fe-Mn-C system at 2.5%Mn Mass u-fraction to show a paraequilibrium calculation where there is formation of para-pearlite. It is an isopleth calculation and shows the STEP_WITH_OPTIONS command using the Paraequilibrium option.

This uses the TCFE database. A license is required to run the example.

This example uses an Fe-Mn-C system at 700 °C to show a paraequilibrium calculation where there is formation of para-pearlite. It is an isothermal calculation and shows the STEP_WITH_OPTIONS command using the Paraequilibrium option.
