abstract = {Fully ferritic stainless steels, strengthened by Laves
phase precipitates, were developed for high-temperature
application in the next generation of ultra-super-critical
thermal power plants. Based on the rapid occurrence of
thermomechanically induced precipitation in strengthening
Laves phase particles, a novel thermomechanical process
route for this class of steels was developed. A controlled
precipitation of particles, in a desired morphology and
quantity, and an optimization of the corresponding forging
parameters was achieved on a laboratory scale. This article
outlines the very first up-scaling experiment with these
optimized forging parameters from the laboratory scale to
the industrial scale. The precipitation behavior was
analyzed, utilizing digital particle analysis of scanning
electron microscopy (SEM) images, to estimate and compare
the phase fraction of the precipitated Laves phase, as well
as the particle size and distribution. Due to the up-scaling
in the forging process, the behavior of the precipitation
changed and the precipitation strengthening effect was
decreased, in comparison with the laboratory scale.},
