Abstract

Accelerated technique has been developed for evaluation of intergranular stress corrosion cracking (IGSCC) initiation behavior of non-sensitized materials in pressure water reactor environment by means of the implementation of hollowed cylindrical specimens under slow strain rate tensile. Typical IGSCC feature was observed on the fracture surface. The crack depth distribution showed two peaks feature which relates to the worked hardened layer on the inner surface. The specimens tested at lower strain rate showed higher fraction of IGSCC, larger number of cracks initiation, shorter elongation and smaller crack opening displacement, suggesting the transition behavior of IGSCC initiation and short crack growth.
