The following bugs have been found in FactSage 8.2. These bugs were not present in FactSage 8.1 or earlier versions. The present patch will correct these bugs.
Bug # 1: When translating input files into ChemSage format, the created files will be in error if dormant (metastable) phases are included.
Bug # 2: When using the viscosity module to calculate the viscosity of liquid/glass oxides, the calculations will be in error if Na2O and B2O3 are both present or if K2O and B2O3 are both present.
Bug # 3: Errors may be encountered in calculations involving the liquid phase in certain ternary and higher-order systems with the databases SpMCBN, FSstel, FTlite, FScopp, FSlead and FTsulf. Binary (two-component) systems are not affected. Only the liquid phase is affected.
Summary of systems affected in the FTsulf database
(Errors might occur only when the MAT2 liquid phase is involved and only when 3 or more metallic elements are present.)
Fe-Cu-Mn
Fe-Cu-Ni
Fe-Cu-Co
Fe-Cr-Mn
Fe-Cr-Ni
Summary of systems affected in the FSStel database
(Errors might occur only when the liquid phase is involved and only when 3 or more elements are present.)
In general,
(1) Low carbon steel: no significant influence
(2) Stainless steel: no significant influence
(3) Medium and high carbon steels containing high W, Nb and Mo have a certain noticeable difference in their liquidus temperature (about max 5 to 20 K).
· Fe-C-W system (high W containing steel; W > several %)
· Fe-C-Nb-Ti system (simultaneously high Nb and Ti; Nb > several % and Ti > several %)
· Fe-C-Mo system (high Mo containing steel; Mo > several %)
(4) Super-alloys containing the following ternary system as a major alloy system have a noticeable difference (about max 30~50K) in their liquidus temperatures.
· Cr-Fe-V
· Fe-Mo-Ni
· Co-Cr-W
· Co-Ni-W
· Cr-Ni-W
· Mo-Ni-Ta
