abstract = {Tungsten alloyed high-chromium ferritic steels such as the
commercially available alloy Crofer 22 H have been proposed
as construction materials for interconnects in Solid Oxide
Fuel Cells. The background of the present study relates to
the qualification of such alloys, especially with respect to
a possible optimization of the tungsten concentration,
aiming at formation of the strengthening intermetallic
phases. For this purpose the chemical composition of
intermetallic phases in a number of Fe-Cr-W-base model
alloys after exposure at temperatures between 600 °C and
900 °C was measured by SEM/EDX and TEM/EDX. The obtained
chemical and phase compositions were used for estimation of
the iron-rich corner of the Fe-Cr-W system in the
temperature range 600–900 °C. Finally, the experimental
results were compared with values calculated using the
Thermocalc software and the database TCFE 7. This comparison
showed that in the temperature range 800 °C–900 °C the
calculations gave a qualitatively correct description of
phases present in the microstructure, however, substantial
differences between calculations and experiments existed in
the temperature range 600 °C–700 °C. Moreover, it was
found that the solubility of silicon in the C14 Laves phase
of the type Fe2W is substantially smaller than that in the
Fe2Nb based laves phase present in Crofer 22 H.},
