Influencing factors on secondary recrystallization in an oxide-dispersion-strengthened ferritic alloy
Original language description
Secondary recrystallization is a key mechanism to produce a microstructure combining high volume fraction of particles and coarse grains which is favorable for low creep strain rates at very high temperatures. However, processing is very sensitive as minor changes can have a huge impact on the final grain size. To elucidate the behavior of secondary recrystallization, this work investigates the effect of different additions of metallic yttrium and a varying consolidation process of a ferritic Fe-Al-Cr based ODS alloy with 5 vol% of nanooxides, called FeAlOY, on the secondary recrystallization process during final annealing at 1100 degrees C. The grain size changes from the order of 100 nm in the hot-consolidated state to a final size of 1-10 mm. The so-called abnormal grain growth occurs after a certain incubation time and when initiated, it takes approx. 20 min. The incubation time of secondary recrystallization increases with increasing rolling intensities and Y-contents, resulting in larger grains. Especially high deformations during hot-rolling yield comparably large grains after annealing. The onset and kinetics of secondary recrystallization are therefore modeled and discussed with respect to the grain- and oxide size evolution during annealing, giving insights into the mechanism of secondary recrystallization.
