AgCl-induced hot salt stress corrosion cracking in a titanium alloy
نویسندگان
چکیده
The mechanism of AgCl-induced stress corrosion cracking Ti-6246 was examined at 500 MPa and 380 °C for 24 h exposures. SEM STEM-EDX examination a FIB-sectioned blister crack showed that metallic Ag formed migrated along the crack. TEM analysis also revealed presence SnO2 Al2O3 products mixed into TiO2. fracture surface has transgranular nature with brittle appearance in primary α phase. Long, straight non-interacting dislocations were observed fractured grain, basal pyramidal traces. This is consistent dislocation emission view mechanism.

Corrosion Product Film-Induced Stress Facilitates Stress Corrosion Cracking
Finite element analyses were conducted to clarify the role of corrosion product films (CPFs) in stress corrosion cracking (SCC). Flat and U-shaped edge-notched specimens were investigated in terms of the CPF-induced stress in the metallic substrate and the stress in the CPF. For a U-shaped edge-notched specimen, the stress field in front of the notch tip is affected by the Young's modulus of th...
متن کاملEffect of Hydrogen on Corrosion and Stress Corrosion Cracking of AZ91 Alloy in Aqueous Solutions
The effect of hydrogen on the corrosion and stress corrosion cracking of the magnesium AZ91 alloy has been investigated in aqueous solutions. Hydrogen produced by corrosion in water diffuses into, and reacts with the Mg matrix to form hydride. Some of the hydrogen accumulates at hydride/Mg matrix (or secondary phase) interfaces as a consequence of slow hydride formation and the incompatibility ...
