- Abstract
It is one of the main failure forms that stress corrosion cracking (SCC) of nickel base alloys and stainless steels in the nuclear pressure vessels and piping. Current researches show that SCC is a process of oxide film rupture and reform. To understand the micro-mechanical state at the SCC crack tip, the stress distribution in oxide film and base metal is analyzed before and after the oxide film rupture, and the effect of groove-type crack length on the stress field at SCC crack tip is also discussed in this paper. The investigated results provide a new insight into the mechanism of SCC growth of the nuclear structural materials in a high water environment.
