FactSage light metals database - list of systems and phases

FactSage FSlite light metal alloy database

List of systems and phases

The following tables summarise the contents of the FactSage FSlite light metal alloy database in terms of the systems and phases it includes. The listings assist in phase selection for particular calculations by providing

- A LIST OF all the unary, binary, ternary and quaternary SYSTEMS WHICH HAVE BEEN ASSESSED

- A LIST OF ALL ASSESSED phases IN EACH OF THE SYSTEMS

- ASSiSTANCE WITH PHASE SELECTION

Phase diagrams have been calculated for all the binary systems using the assessed parameters contained in the database. The diagram for a particular binary system can be viewed by clicking on the system as listed in Table 2 below. The diagrams contain the names of the stable phases in each system and thus provide guidance in phase selection for calculations in higher-order systems.

The phases listed for the binary and higher order systems may be solution phases or stoichiometric intermetallic compound phases (ST).

Use of the FactSage module VIEW DATA with FSlite compound and solution databases allows inspection of a phase listing for a defined combination of elements.

When searching for a particular system in the present four lists, use alphabetical order of the elements.

A list of references for the individual system assessments can be found under "General Documentation" on the present menu.

Table 3: List of phases for TERNARY systems

Assessed ternary parameters are available only for those phases listed in blue below. Thermodynamic values for other ternary phases listed are obtained from the relevant binaries by application of the particular model used in the database. Some of the tabulated phases are present only in the constituent binary systems.

Beware - if some ternary phases are unknown, or have not been included in the published assessments from which the present data have been selected, incorrect phase equilibria may be calculated.

Phases accompanied by ST in parenthesis indicate a stoichiometric phase. The phase must be selected from the FSlite compound base.

(I-option) – the phase displays a miscibility gap or is an ordered phase; selection with the I-option required.

Comments in red for each system provide a rough guideline with respect to composition ranges covered by the assessed data and hence to which calculations should be restricted.

Table 4: List of phases for QUATERNARY systems

Assessed quaternary parameters are available only for those phases listed in blue below.

Thermodynamic values for other quaternary phases listed are obtained from the relevant binaries and ternaries by application of the particular model used in the database. Some of the tabulated phases are present only in the constituent binary and ternary systems.

Beware - if some ternary or quaternary phases are unknown, or have not been included in the published assessments from which the present data have been selected, incorrect phase equilibria may be calculated.

Phases accompanied by ST in parenthesis indicate a stoichiometric phase. The phase must be selected from the FSlite compound base.

(I-option) – the phase displays a miscibility gap or is an ordered phase; selection with the I-option required.
