• The total number of stored phase diagrams has been increased by over 700.

  

In FactSage all private files created by these modules have the naming convention PROG*.dat, where

- PROG is EHPH, PRED, REAC, EQUI, PHAS and MIXT that correspond to the modules EhPh, Predom, Reaction, Equilib, Phase Diagram and Mixture.

- * are user-supplied digits 1 - 9999 or alphanumeric descriptions.

- for example, EHPH1234.dat, PREDFe-SO2-O2.dat, REACH2_plus_O2.dat, EQUIFeO-slag.dat, PHASCaO-SiO2_TvsX.dat, MIXTAir.dat

In FactSage the file extension *.dat is not limited to the modules above. For example, ChemSage files also employ the same file extension.

With the Windows Explorer it is difficult to manipulate the files since one cannot order the files by type (file extension). Options 'Save' and 'Save as ..' within the above modules are not supported by the Windows Explorer and so it can be a challange naming or re-naming the file without access to the current list of file names.

In FactSage 8.0 the file naming convention PROG*.dat has been replaced by a more versatile *.prog. That is, the new file names are *.ehph, *.pred, *.reac, *.equi, *.phas and *.mixt.

For the examples above the new file names are now:

       - 1234.ehph, Fe-SO2-O2.pred, H2_plus_O2.reac, FeO-slag.equi, CaO-SiO2_TvsX.phas, Air.mixt

Old PROG*.dat files will still remain accessible to the FactSage 8.0 modules. However new user files will now have the naming convention *.prog. That is, a folder may contain a combination of both formats say EQUI1.dat, EQUI2.dat, 3.equi and 4.equi.

In the Equilib Directory Window where you select and load stored systems these systems will appear as Equilib Files 1, 2, 3, and 4. If click 'File >' you can select a new option 'Rename all EQUI*.dat files as *.equi'. In the above example you would end up with 1.equi, 2.equi, 3.equi and 4.equi.

It should be noted that the new files *.prog will not accessible to FactSage 7.3 and prior installations. (To make a file accessible you must rename it as PROG*.dat - see the new option in Equilib Directory Window).

• What's New in View Data - 'View Data > Help > What's New in View Data ...'

  The link What's New in View Data has been updated and gives a summary of the more important programming changes in View Data that have appeared since FactSage 6.1 (2009) until now FactSage 8.0 (2020).

• Total number of components

  The summary of data for compounds now includes the total number of components (elements). For example the FactPS pure substances database includes 91 elements.

  
  

• What's New in Equilib - 'Equilib > Reactants Window > Help > What's New in Equilib ...'

  The link What's New in Equilib has been updated and gives a summary of the more important programming changes in Equilib that have appeared since FactSage 6.1 (2009) until now FactSage 8.0 (2020).

• What's New in Macro Processing - 'Equilib > Reactants Window > File > Macro Processing > What's New in Macro Processing ...'

  The link What's New in Macro Processing has been updated and gives a summary of the more important programming changes in Macro Processing that have appeared since FactSage 5.5 (2007) until now FactSage 8.0 (2020) .

• Macros and the new file naming convention - *.equi, *.phas, *.mixt

  In FactSage 8.0 private files PROG*.dat have been replaced by *.prog files.

  The macro function $EXIST() and the macro commands OPEN and SAVE have been modified and are backward compatible it is not necessary to apply the new naming convention to old *.mac files. That is, you can load and run old *.mac files and not worry about the new naming convention.

  $EXIST()

  
  $EXIST('FileName')        // = 1 if 'FileName' exists  
  $EXIST(EQUIEx_CH4-O2.dat) // FactSage 7.3 (and prior) naming convention
  $EXIST(Ex_CH4-O2.equi)    // FactSage 8.0 naming convention
  

  The macro function $EXIST is backward compatible.
  For example, $EXIST(EQUIEx_CH4-O2.dat) returns a value 1 if the file Ex_CH4-O2.equi exists.

  OPEN

  
  OPEN 'FileName'        // open (load) Equilib and Phase Diagram files 
  OPEN EQUIEx_CH4-O2.dat // FactSage 7.3 (and prior) naming convention
  OPEN Ex_CH4-O2.equi    // FactSage 8.0 naming convention
  

  The macro command OPEN is backward compatible.
  For example the command OPEN EQUIEx_CH4-O2.dat opens the file Ex_CH4-O2.equi if it exists.

  SAVE

  
  SAVE 'Mixture' GAS (LIQUIDS SOLIDS SOLUTIONS 'phase-name')  // save results in a stream 
  SAVE MIXTMyGas.dat GAS // FactSage 7.3 (and prior) naming convention
  SAVE MyGas.mixt GAS    // FactSage 8.0 naming convention 
  

  The macro command SAVE 'Mixture' is backward compatible.
  For example SAVE MIXTMyGas.dat saves the mixture in MyGas.mixt.

  Macro example

  For an example of backward compatibility run the macro EquiEx_SET_Variables.mac located in the Macros Directory.

  The macro log file posts '-------> Backward compatible: ...' each time the issue is encountered.

• Encrypted macros

  In FactSage 8.0 it is now possible to encrypt a macro file (*.mac) and create an encrypted macro file (*.mace).

  To perform the encryption go to the Equilb Reactants Window. 1. Click 'File > Macro processing ... > Encrypt macro ...' and open the macro file (*.mac) you wish to encrypt. 2. The resulting encrypted macro file (*.mace) will be stored in the same location as the source file. 3. Note there is no option to decipher the encrypted macro.

  The advantages of an encrypted macro file are:

  • Security.
    The encrypted file cannot be modified or edited. Any attempts to do so render the file corrupt and useless.

  • Confidentiality.
    The contents of the original macro source file are hidden.

    When the macro processing is run the lines of code are displayed in real time in the Macros Window. Use the macros command PRINTOFF to suppress the output and hide the code. Use PRINTON to reactivate the output. See the example below for the commands PRINTOFF and PRINTON.

  • Mobility. The encrypted file is a simple text file that can be copied and emailed as an attachment.

  The encrypted macro file (*.mace) is employed in macro processing in the same manner as a normal macro file (*.mac).

• Limiting macro access to a given user ID

  The macro functions $USERID and $USERNAME provide the user ID (1-9999) and company name or affiliation.

  Let us say you wish to give macro access only to customer ID 123 Company A-B-C.
  Insert the following commands into the macro file.

  DIM %ID %NAME %ID = $USERID %NAME = $USERNAME PRINTOFF // The following lines will NOT appear in the Macros Window. IF %ID <> 123 THEN // i.e. if ID is not 123 %TITLE = User ID %ID %NAME MSGBOX Access limited to ID 123 - Company ABC GOTO END // terminate the macro processing ENDIF PRINTON // The following lines will appear in the Macros Window. ...

  To permit access to only IDs 123, 456 and 789 use:

  IF %ID <> 123 AND %ID <> 456 AND %ID <> 789 THEN
  

  To block access to all except IDs 200 - 300 use:

  IF %ID < 200 OR %ID > 300 THEN
  

  When finished remember to encrypt the macro file.

The Viscosity module calculates the viscosity of single-phase liquid slags (melts) and liquid glasses.

In FactSage 8.0 a new component, Li2O, has been added to the viscosity databases for both Melts and Glasses. The new lists of components are:

Al2O3-B2O3-CaO-FeO-Fe2O3-K2O-Li2O-MgO-MnO-Na2O-NiO-PbO-SiO2-TiO2-Ti2O3-ZnO-F melts
      and
Al2O3-B2O3-CaO-K2O-Li2O-MgO-Na2O-PbO-SiO2 glasses.

• FactPS is the compound database for use with the FACT databases (FToxid, FTsalt, etc.).

• Data for the thermal expansion, isothermal compressibility, pressure derivative of the bulk modulus and thermal conductivity for the following compounds have been updated (92 phases):

  Al2O3 (S1, S2, S3, S4) Al2Si2O7 BaO Ca2Al2SiO7 Ca2Fe2O5 Ca2SiO4 (S1, S2, S3) Ca3Al2O6 Ca3MgSi2O8 Ca3Si2O7 Ca3SiO5 CaAl12O19 CaAl2O4 CaAl2Si2O8 (S1, S2) CaAl4O7 CaCr2O4 (S1, S2) CaFe2O4 CaMgSi2O6 CaO

  NaNO3 NaRb3(NO3)4

• FactPS 8.0 now contains 4928 compounds (was 4920) and 7046 phases (was 7036).

• FTdemo is the name for the old FACT Slide Show database developed around 2001. Although FTdemo is part of FACT Package of Databases, it is for demonstration calculations only. It should be used only for teaching - for example with the Slide Shows.

• For calculations where the results are important, you must NOT use the FTdemo database. Use the FactPS compound database and the FToxid, FTsalt, etc. databases. For detailed information on the FactPS, FToxid, FTsalt, etc. databases go to the FactSage Main Menu and click on Documentation.

The FThall database contains the elements Al-Mg-Na-Li-Ca-F-O-C. It is used for thermodynamic and phase equilibrium calculations involving liquid metal - cryolitic bath - Al2O3-based oxides in alumina reduction electrolysis cells, and for molten aluminum treatment with fluoride fluxes.
• In FactSage 8.0 data for the thermal expansion, isothermal compressibility, pressure derivative of the bulk modulus and thermal conductivity for the following compounds have been updated (26 phases):

  LiF, NaF, MgF2(s1), Al4C3, Na3AlF6(s1), Na3AlF6(s2), Na5Al3F14, Na2LiAlF6(s1), Na2LiAlF6(s2), CaF2(s1), CaF2(s2), LiCaAlF6, NaCaAlF6(s1), NaCaAlF6(s2), NaCaAlF6(s3), Na2Ca3Al2F14, Na4Ca4Al7F33, Li2O, MgO, CaO, Al2O3(s1), Al2O3(s2), Al2O3(s3), Al2O3(s4), NaAl9O14, CaAl12O19.

  The thermal conductivity and the volumetric properties are only calculated if the 'include molar volume data and physical property data' option is checked.

FTlite is primarily designed for thermodynamic and phase equilibrium calculations involving Al alloys and Mg alloys. Calculations involving Ti alloys and Li-Na-K-Mg-Ca-Sr-Ba mixtures can also be performed but not to the extent as for Al- and Mg-alloys. In FactSage 7.3 there was a major update and restructuring of FTlite. Extensive and detailed Tables listing the important solutions for calculations involving Al alloys, for solutions in Mg-alloys, and a detailed list of all solutions were given in new documentation (78 pages total!) In FactSage 8.0 the help section dealing with the selection of phases and species has been revised. This important information now appears near the beginning rather than at the end of the documentation file.

Minor update: - there is a correction to the volumetric properties of the Ag(fcc) pure substance in the compound database (s1) and to the FCC_A1 phase in the solution database.

• The addition of Li2O to FToxid is a major update.

• Li2O has been added to the Na2O-CaO-MgO-Al2O3-SiO2 system. All binary and ternary subsystems have been optimized. The predictions of the models have been checked against a limited amount of experimental data available for the Li2O-CaO-Al2O3-SiO2, Li2O-MgO-Al2O3-SiO2 and Li2O-Na2O-Al2O3-SiO2 quaternary subsystems. When needed, small quaternary parameters were added for the liquid phase to approximately fit the data.

• The most important subsystems containing both Li2O and K2O, i.e. Li2O-K2O-SiO2 and Li2O-K2O-Al2O3-SiO2, have been approximately optimized, and the limited experimental information on the Li2O-Na2O-K2O-SiO2 quaternary has been checked. Hence, reasonable calculations are expected for the whole Li2O-Na2O-K2O-CaO-MgO-Al2O3-SiO2 system.

• The database can also be used to make calculations in systems containing both Li2O and F up to about 50% of fluorides. The thermodynamic properties of the liquid phase are most accurate for the Li2O-Na2O-K2O-CaO-MgO-Al2O3-SiO2-F liquid.

• 36 new stoichiometric compounds and 11 new solid solutions have been added to the database; 10 solid solutions have been modified.

• The K2O-P2O5 system has also been reoptimized.

• 57 phase diagrams have been added (35) or modified (22). The total number of stored FToxid phase diagrams is now 490 (was 455 in 7.3).

The FTsalt databases contain data for pure salts and salt solutions of 27 main cations:

Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Mn, Al, Fe(II), Fe(III), Co, Ni, Zn, Pb, La, Ce, Th, U(III), U(IV), Pu(III), Pu(IV), Cr(II), Cr(III), Mo(V)

and 9 main anions:

F, Cl, Br, I, NO2, NO3, OH, CO3, SO4 as well as for dilute solutions of O2- and OH- in the molten salt phase.

In FactSage 8.0 the updates to FTsalt include the following changes.

• NO2 is a new anion.

• The NaNO3-KNO3-NaNO2-KNO2 ternary reciprocal system has been evaluated and optimized at all compositions. A new list of components(SALTK) related to this system has been added in the SALT liquid solution. The NaNO3-KNO3 binary system now displays two terminal high temperature solid solutions (in FTsalt 7.3 there was only a single high temperature solid solution).

• The solid solutions, Arag and hR24, have been extended with the addition of nitrites; the G01 solid solution has been adjusted; four new solid solutions, KN_I, NaNB, KNA_, KNB_, have been introduced.

• Three new compounds,NaNO2, KNO2 and Na2(NO3)(NO2), have been added and data on the seven compounds, NaNO3, KNO3, K2Cl(NO3), K2OH(NO3), Na2OH(NO3), Na3(OH)2(NO3) and NaRb3(NO3)4 , have been revised.

• Due to the above changes ten NaNO3-containing common-ion binary systems and ten KNO3-containing common-ion binary systems have been adjusted. The corresponding calculated phase diagrams are very similar to the previous ones.

The total number of stored FTsalt phase diagrams is now 344 (was 338 in 7.3).

Complete details on FTsalt including all the phase diagrams are given in Documentation in the FactSage Main Menu Window.

Minor update: - there is a correction to the volumetric properties of the Ag(fcc) pure substance in the compound database (s1) and to the FCC_A1 phase in the solution database.

Minor update: - there is a correction to the volumetric properties of the Ag(fcc) pure substance in the compound database (s1) and to the FCC_A1 phase in the solution database.

In FactSage 8.0 the FSstel database now includes Zn and AlMgSi galvanizing bath chemistry for steel coatings various compositions ranges of super alloys including MCrAlY various composition ranges of High Entropy Alloy (HEA) including FCC and BCC order/disorder transitions. With hydrogen (H) now included in the database, the hydrogen solubilities in liquid and solid FCC, BCC, HCP, etc. are well represented. The updates for P and N-containing systems are done as a continuation from FSstel 7.3. The model parameters for 18 new binary systems and 10 new ternary systems, as well as several quaternary system, are now included.

full size

In summary, the following systems have been updated:

• Correction of the phase boundary of FCC order/disorder transition in Al-Fe system. No significant change in any Fe-rich region in FSstel 7.3.

• Addition of binary M-H systems where M = Al, Cr, Cu, Fe, Mg, Ni, Si, Ti, V, Zr. Liquid, FCC, BCC and HCP solutions and important metal hydrate phases are included. In addition, liquid phase in the Ca-H and Zn-H systems are included.

• Updates of Al-Co-Cr-Fe-Ni-Ti system for BCC-B2 and FCC-L12 containing alloys (many binary and ternary systems containing FCC and BCC order/disorder transitions were updated). This system is also well connected to Mn. The new database can give satisfactory results for high entropy alloys (HEAs) of Al-Co-Cr-Fe-Mn-Ni, MCrAlY alloys, and other high alloys
  Binaries: Al-Co (FCC is slightly changed)
  Ternaries: Al-Co-Ni, Al-Cr-Ni, Al-Cr-Ti, Co-Cr-Ni, Co-Ni-Ti

• Al-Fe-Zn-Mg-Si-H (all binary systems and key ternary systems) for Zn galvanizing and new AlMgSi galvanizing alloy systems. No significant update was made but the addition of hydrogen in liquid was carried out (see M-H above)

• Minor updates for several systems: Ni-Zr, Sn-Ti, Sn-V, Si-Sn-Ti

The total number of stored FSstel phase diagrams is now 221 (was 198 in 7.3).
