abstract = {In the present study the long-term behaviour of two
ferritic steels, Crofer 22 APU and Crofer 22H, in contact
with a Ni-mesh during exposure in simulated anode gas,
$Ar–4\%H2–2\%H2O,$ at 700 and 800 °C for exposure times
up to 3000 h was investigated. Ni diffusion from the Ni-mesh
into the steel resulted in the formation of an austenitic
zone whereas diffusion of iron and chromium from the steel
into the Ni-mesh resulted in the formation of chromia base
oxides in the Ni-mesh. Depending on the chemical composition
of the steel, the temperature and the exposure time,
interdiffusion processes between ferritic steel and Ni-mesh
also resulted in σ-phase formation at the
austenite–ferrite interface and in Laves-phase dissolution
in the austenitic zone. The extent and morphology of the
σ-phase formation are discussed on the basis of
thermodynamic considerations, including reaction paths in
the ternary alloy system Fe–Ni–Cr.},
