abstract = {High-performance Ferritic (HiperFer) steels are a novel
class of heat-resistant, fully ferritic, Laves phase
precipitation hardened materials. In comparison to
conventional creep strength-enhanced 9–12 $wt.\%$ Cr
ferritic–martensitic steels, HiperFer features increased
mechanical strength, based on a thermodynamically stable
distribution of small (Fe,Cr,Si)2(Nb,W) Laves phase
precipitates, and—owing to its increased chromium content
of 17 $wt.\%—improved$ resistance to steam oxidation,
resulting in superior temperature capability up to 650 °C.
Previous publications focused on alloying, thermomechanical
processing, and basic mechanical property evaluation. The
current paper concentrates on the effect of heat treatment
on microstructural features, especially Laves phase
population, and the resulting creep performance. At 650 °C
and a creep stress of 100 MPa, an increase in rupture time
of about $100\%$ was achieved in comparison to the solely
thermomechanically processed state.},
