abstract = {In the present study a stainless, high strength, ferritic
(non-martensitic) steel was analysed regarding
microstructure and particle evolution. The preceding
hot-rolling process of the steel results in the formation of
sub-grain structures, which disappear over time at high
temperature. Besides that the formation of particle-free
zones was observed. The pronounced formation of these zones
preferentially appears close to high angle grain boundaries
and is considered to be responsible for long-term material
failure under creep conditions. The reasons for this are
lacking particle hardening and thus a concentration and
accumulation of deformation in the particle free areas close
to the grain boundaries. Accordingly in-depth investigations
were performed by electron microscopy to analyse dislocation
behaviour and its possible effect on the mechanical response
of these weak areas.},
