摘要: The sigma-phase precipitation in 20% cold-worked 15Cr-15Ni titanium-modified austenitic stainless steel was studied during long-term aging treatment. During the isothermal aging stage, the amount of sigma-phase was significantly increased at beginning and gradually became constant. The aging time only slightly affected the size and morphology of the sigma-phase. Conversely, during the isochronal aging stage, the amount of sigma-phase grew rapidly with the increase in the aging temperature. The sigma-phase with a large amount of stacking faults was prone to nucleate around the (Ti, Mo) C particles or at the grain boundaries. The (Ti, Mo) C particles can act as effective nucleation sites, where the sigma-phase directly precipitates from the austenitic matrix. From this work, the growth of sigma-phase is found to be influenced by the aging temperature, and a new mechanism of sigma-phase precipitation from austenite has been proposed.
