Studies monitoring cavity nucleation with strain after creep deformation has limited information with varying applied stresses. In this work, a large number of experiments were performed to investigate cavity nucleation at different stresses for a primary reformer tube. It has been found that with the increase in stress, cavity formation increases drastically, which is more prone to nucleate at grain boundary triple junctions rather than grain boundaries where the extent of initial inclusions/other second phase particles was kept unaltered.
