SCC of the steel in the solution can notbe reasonably explatined by the passive film rupture-repassivation theory and by thehydrogen embrittlement theory. It is believed that the fracture stress at the tip of cracks is re-duced by anodic dissolution due to its role in relieving strain hardening layer at crack tip. Key words:  stress corrosion cracking      stainless steel      anodic dissolution      Received:  18 May 1993      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1993/V29/I5/68 1 Hoar T P, Hinse J G.
