TLDR
In this article, the inconsistency between the measured and computed enthalpies of formation via CALPHAD method for the ternary compounds is traced to the Fe-Si system in which there is a disagreement between the experimental enthalpy of formation and CALPAD type one.About:

Effects of Si additions on intermetallic compound layer of aluminum–steel TIG welding–brazing joint
TL;DR: In this paper, a TIG welding-brazing with 1100 pure Al, 4043 AlSi5 and 4047 AlSi12 filler metals was used to butt join 5A06 aluminum alloy and AISI 321 stainless steel.

The Al-Rich Part of the Fe-Al Phase Diagram
TL;DR: In this paper, a series of 19 alloys were produced and heat-treated at temperatures in the range from 600 to 1100 °C for up to 5000 Â h. The obtained data were further complemented by results from a number of diffusion couples, which helped to determine the homogeneity ranges of the phases FeAl2, Fe2Al5, and Fe4Al13.

SGTE data for pure elements
TL;DR: In this article, the authors present the data for the condensed phases of 78 elements as currently used by SGTE (Scientific Group Thermodata Europe) as a sound basis for the critical assessment of thermodynamic data, thereby, perhaps, limiting unnecessary duplication of effort.

The Thermo-Calc databank system☆
TL;DR: Using the facilities of Thermo-Calc one can tabulate thermodynamic data, calculate the heat change of chemical reactions and their driving force, evaluate equilibria for chemical systems and phase transformations and calculate various types of multicomponent phase diagrams by an automatic mapping procedure.
