Abstract

The relationship between corrosion behavior and stress corrosion cracking (SCC) is bridged in ZX10-xSn (0 ≤ x ≤ 2) alloys. Specifically, severe localized corrosion serves as a crack initiation source and causes film rupture and hydrogen accumulation, resulting in high susceptibility index of SCC (I_SCC). Among the five alloys, ZX10–1.5Sn boasts the lowest I_SCC, with an I_εf of ∼2 % for pre-immersed samples and ∼63 % for immersed samples, owning to its uniform corrosion. This significant difference in I_εf suggests that enhanced hydrogen penetration due to external forces, rather than the corrosion products, plays a more critical role in deteriorating mechanical properties.
