FactSage Internet access is a new option in FactSage 8.3

This option only applies to FactSage accessing the internet. It has no effect on the computer connection to the internet - for example 'Airplane mode - on/off'.

'Internet > On - internet access' - permits FactSage to access the intenet if the computer is connected to the internet. This is the recommended setting. 'Internet > Off - no internet' - as shown here - stops FactSage from accessing the internet (e.g. to download files, to send your IP address to www.factsage.com, to display internet web pages) even if the computer is connected to the internet. This is not recommended as it will block updates of the profiles file and hide important messages from www.factsage.com.

The icons of the active FactSage Apps posted in the desktop taskbar use the same letter . This can be confusing.

In FactSage 8.3 icons of active FactSage Apps reflect the name of the App
- Compound, Calphad Optimizer, Equilib, EpH, FactSage, Figure, Mixture, Phase Diagram, Predom, Reaction, Solution, View Data, Viscosity, Fact-XML.

• In FactSage 8.3 the total number of stored phase diagrams has been increased by over 200.

  

• 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 8.3 (2023).

• What's New in Phase Diagram - 'Phase Diagram > Components Window > Help > What's New in Phase Diagram ...'

  The link What's New in Phase Diagram has been updated and gives a summary of the more important programming changes in Phase Diagram that have appeared since FactSage 6.1 (2009) until now FactSage 8.3 (2023).

• Running multiple instances of Phase Diagram

  With the FactSage Add-ons menu it is now possible to run multiple instances (i.e. copies of the software) of Phase Diagram. That is, it is possible to have separate copies of Phase Diagram running simultaneously but independently from each other. This is analagous to running multiple instances of Equilib as shown elsewhere.

In FactSage 8.2 the viscosity algorithm was completely restructured. The Viscosity App performs calculations approximately ten times faster than in earlier FactSage versions and there are no issues to report in FactSage 8.3.

In FactSage 8.3. new options have been added to Data Search Window. Import TDB databases It is now possible to import a Thermochemical Database (TDB) format database to the 'List of databases' posted in the Data Search Window. Click the Add/Remove Data button and then click on the new IMPORT option to first import the TDB database (*.tdb) and convert it to FactSage compound and solution databases (*.cdb, *.sln). If successful you will then see the option to Register the database and ADD it to the 'List of databases'.

Private databases in \PRIVDATA

All private compound (*.cdb) and solution (*.sln,*.fdb) databases stored in the \PRIVDATA folder (typically c:\FactSage\PRIVDATA) are now automatically registered and added to the 'List of databases' posted in the Data Search Window.

The old manual way is still available (i.e. click Add/Remove Data > Add > filename etc.) but storing the files in the \PRIVDATA folder avoids performing this manual task.

• FactPS is the compound database for use with the FACT 8.3 databases (FToxid, FTsalt, etc.).

• 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.

FTlite is designed for thermodynamic and phase equilibrium calculations involving Al alloys, Mg alloys and Ti alloys. It can also be used to perform calculations involving mixtures of Li-Na-KMg-Ca-Sr-Ba with several other elements.

FTlite 8.3 binary assessments full size

In FTlite 8.3, a total of 992 binary systems (was 932 in 8.2) have been evaluated, for most of them over the entire range of composition and for all stable phases.

A matrix of assessed binary systems is shown here for the major and minor alloying elements of Al-, Mg- and Ti-alloys.

Several dozens of ternary systems have been assessed, and important quaternary systems have also been evaluated.

FTlite 8.3 contains 317 solution phases (vs 287 in 8.2) and 2145 pure compounds (was 1926 in 8.2) with 2621 stoichiometric phases counting allotropic forms (2374 in 8.2).

The total number of stored FTlite phase diagrams is now 1045 (was 982 in 8.2).

Complete details on FTlite 8.3 including all the phase diagrams are given in the updated Documentation in the FactSage Main Menu Window.

The FToxid databases contain data for pure oxides and oxide solutions of over 20 elements as well as for dilute solutions of S, SO4, PO4, H2O/OH, CO3, F, Cl and I in the molten (slag) phase. FToxid 8.3 is included in the FACT 8.3 package of databases.

In FactSage 8.3 the updates to FToxid include the following:

• New optimizations of Ti-containing systems:
  TiO2-Ti2O3 + CaO-MgO-FeO-Fe2O3-MnO-Mn2O3-Al2O3-SiO2

• Complete reoptimizatuon of the most important solid solutions:
  Rutile, Ilmenite, Pseudobrookite and Ti-spinel

• Update of other solid solutions:
  Monoxide (Ti2O3 added), Corundum, Ca3Ti2O7-Ca3Ti2O6, Perovskite and Tetragonal-spinel

• New or modified data for about a dozen stoichiometric Ti-containing compounds.

Complete details on FToxid 8.3 including all the phase diagrams are given in the updated Documentation in the FactSage Main Menu Window.

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 10 main anions:

F, Cl, Br, I, NO2, NO3, ClO4, OH, CO3, SO4 as well as for dilute solutions of O2- and OH- in the molten salt phase.

In the compound FTsalt database new compounds Mg(NO3)2, Mg(NO2)2, Mg(ClO4)2(s1,s2,s3), K2Mg(CO3)2 and K2Mg(NO3)4(s1,s2) have been added and existing compounds MgCO3, CeCl3, Na3Ce5Cl18, K2CeCl5, K3CeCl6, K3Ce5Cl18, RbCe2Cl7, Rb2CeCl5, Rb3CeCl6, CsCe2Cl7 and Cs3CeCl6 have been modified.

In the solution FTsalt database new liquid solutions SALTL (K, Mg // NO3, NO2, Cl, CO3, ClO4) and SALTM (Li, Na, K, Mg, Ca, Ce // Cl) have been added. In addition three new CeCl3-based solid solutions have been introduced : (K,Na)3CeCl6(ss), (K,Na)2CeCl5(ss) and (K,Na)3Ce5Cl18(ss) (with the nicknames A3C1, A2C1 and A3C5, respectively).

The SALTL liquid solution permits calculations for KNO3-rich solutions with MgCO3 or MgX2 contents up to about 5 wt% (where X = NO2, Cl or ClO4). Owing to the lack of phase diagram data, the common-ion binary sub-systems K2CO3-MgCO3, Mg(NO3)2-MgCO3, KNO2-Mg(NO2)2, Mg(NO3)2-Mg(NO2)2, MgCl2-Mg(NO3)2, KClO4-Mg(ClO4)2 and Mg(NO3)2-Mg(ClO4)2 were estimated based on chemically similar systems. For nitrate-rich solutions without Mg solutes, the SALTK liquid solution (currently Li, Na, K // NO3, NO2, Cl, CO3, ClO4) can be used.

The SALTM liquid solution permits calculations for CeCl3-containing solutions with Mg and/or Ca, but without Rb and Cs. The ternary sub-systems LiCl-MgCl2-CeCl3, KCl-MgCl2-CeCl3, LiCl-CaCl2-CeCl3, NaCl-CaCl2-CeCl3 and MgCl2-CaCl2-CeCl3 have been newly evaluated and optimized at all compositions, while the ternary sub-systems LiCl-KCl-CeCl3 and NaCl-KCl-CeCl3 have been substantially improved. For CeCl3-containing solutions with RbCl and/or CsCl, the SALTG liquid solution (Li, Na, K, Rb, Cs, La, Ce // Cl) can be used

The total number of stored FTsalt phase diagrams is now 377 (was 367 in 8.2). FTsalt 8.3 is included in the FACT 8.3 package of databases.

Complete details on FTsalt 8.3 including all the phase diagrams are given in Documentation in the FactSage Main Menu Window.
