摘要：

The intergranular stress corrosion cracking (IGSCC) growth behavior of austenitic stainless steels (SS) in hydrogenated high-temperature water were studied using compact tension specimens (0.5T for cold-worked materials). The effects of carbide precipitation, alloy composition, and the cold rolling direction on crack growth behavior were studied. Then, to examine these influences on IGSCC, grain boundary sliding was studied in high-temperature air. The similar dependences of carbide precipitation, cold work, and rolling direction on IGSCC and creep behaviors suggest that grain boundary sliding plays an important role by itself for in conjunction with other reactions such as crack tip dissolution.
