Research Progress on stress corrosion crack propagation behavior of cold worked nuclear power structural materials in high temperature and high pressure water

Research Progress on stress corrosion crack propagation behavior of cold worked nuclear power structural materials in high temperature and high pressure water

In the early nuclear power plants, the pipes were mainly made of 304SS and 316SS austenitic stainless steel, and stress corrosion cracking (SCC) often occurred in the cold working area of steel pipes. Transgranular stress corrosion (TGSCC) of welded core shroud ...

Research status and development of high temperature and high pressure water notch fatigue properties of nuclear power materials

Research status and development of high temperature and high pressure water notch fatigue properties of nuclear power materials

Corrosion fatigue is one of the potential failure modes of nuclear power materials in service. The results show that the fatigue life of materials in high temperature and high pressure water environment is significantly decreased in light water reactor (LWR). ...
