Recent Advances in Creep Resistant Steels for Power Plant Applications
TL;DR: In this paper, it is shown that the martensitic transformation in these three steels produces high dislocation density that confers significant transient hardening, however, the dislocations density decreases during exposure at service temperatures due to recovery effects and for longterm creep strength the sub-grain structure produced under different conditions is most important.
