TCFE9 TCFE9: TCS Steel and Fe-alloys Database Database name: TCS Steel and Fe-alloys Database Database acronym: TCFE Database owner: Thermo-Calc Software AB Database version: 9.0 Brief Description TCFE is a thermodynamic database for calculation of phase diagrams and thermodynamic properties in steel and Fe-alloys. TCFE can be used with Thermo-Calc, its add-on simulation modules for diffusion (DICTRA) and precipitation (TC-PRISMA), and the Software Development Kits (SDK). Applications Steel and Fe-alloy design and processing, including heat treatment. TCFE includes data for molar volumes enabling the calculation of density, lattice parameters (for cubic structures), coefficients of thermal expansion, and relative length change. However, the incorporated molar volume data (except for pure iron) has no pressure dependence. It can be used with satisfactory results for a range of different alloy types: e.g. stainless steels, high-speed steels, tool steels, HSLA steels, cemented carbides, cast iron, corrosion-resistant high strength steels and more. Included Elements (28) Ar Al B C Ca Ce Co Cr Cu Fe H Mg Mn Mo N Nb Ni O P S Si Ta Ti V W Y Zn Zr Assessed Systems TCFE covers the complete and critical assessments of many important binary and ternary systems, as well as the iron-rich corner of some higher order systems, within the 28-element framework. Note that Ar and H are modelled to take part in the gas phase only, and no modelling of their solubility in the solid solution phases or liquid has been considered in the TCFE database. Limits The database is applicable for various types of steels/Fe-alloys with a Fe-minimum of 50wt%, and for alloying elements the recommended composition limits (in weight percent) are as
