      abstract     = {The oxidation behavior of a number of commercially
                      available ferritic and austenitic steels was tested in air
                      and in two simulated anode gases of a solid oxide fuel cell
                      (SOFC) to evaluate the potential suitability as construction
                      materials for interconnects in SOFC's operating at 600
                      degrees C. During air exposure all studied materials showed
                      excellent oxidation resistance due to formation of a
                      protective, double layered chromia/spinel surface scale even
                      if the steel Cr content was as low as $17\%.$ However, in
                      the anode side gases the presence of water vapour (and
                      possibly CO/CO2) increased the tendency to form poorly
                      protective Fe-base oxide scales, in combination with
                      internal oxidation of Cr. The occurrence of this adverse
                      effect could be suppressed not only by increased Cr contents
                      of the alloy but also by a small alloy grain size either in
                      the bulk of the material Or in the specimen/component
                      surface. The latter can be promoted by cold work e.g.
                      introduced by specimen/component grinding. As high Cr
                      contents may lead to undesired sigma-phase formation and
                      defined surface treatments of an interconnect will not be
                      possible in all designs, the relatively low operating
                      temperature of 600 degrees C, resulting in low Cr
                      diffusivity in the alloy grains, may require the use of a
                      fine grained interconnect material to obtain and sustain
                      protective chromia base surface scale formation during
                      long-term operation. (C) 2010 Elsevier B.V. All rights
