Abstract High Cr/Ni 310S-type austenitic stainless steels (ASSs) exhibit good comprehensive properties of creep-, corrosion- and oxidation-resis-tances, as well as moderate neutron irradiation-resistance, which are potential as fuel-cladding candidate materials applied into the super-critical water reactors (SCWRs). However, one underlying issue for this kind of ASSs is their microstructural stability, i.e., a large amount of coarse Cr₂₃C₆ and σ are precipitated on grain boundaries (GBs) after a long-term aging at 873—1 123 K, as a result of the embrittlement and intergranular corrosion of materials. In order to improve their microstructural stability at high temperatures, the present work investigated systematically the effects of the ratios of strong carbide-forming elements M (M=Nb, Ti, Ta, and Zr) to C (in atomic percent at%), and the stabilization treatment on the precipitation behaviors of 310S ASS. The designed alloy rods were solid-solutioned at 1 473 K for 0.5 h plus water quenched, stabilized at 1 173 K for 0.5 h, and then aged at 1 073 K for 24 h. The microstructure and precipitated phases at different heat-treatment states were characterized with OM, SEM-EDS, EPMA and TEM, respectively. It was found that the addition of M favors to the precipitation of MC-type carbides effectively. A high ratio of M to C (2/1) can accelerate the formation of brittle σ phase, in contrast, only Cr₂₃C₆ precipitates exist on GBs after 1 073 K/24 h aging in alloys with M/C=1/1. In addition, the Cr₂₃C₆ could be inhibited effectively by stabilization heat-treatment. This work provides effective basic data support for the development of fuel cladding materials for SCWRs, and point the way for the further research.
