  The mechanism of AgCl-induced stress corrosion cracking of Ti-6246 was
examined at \SI{500}{\mega\pascal} and \SI{380}{\celsius} for \SI{24}{\hour}
exposures. SEM and STEM-EDX examination of a FIB-sectioned blister and crack
showed that metallic Ag was formed and migrated along the crack. TEM analysis
also revealed the presence of \ce{SnO2} and \ce{Al2O3} corrosion products mixed
into \ce{TiO2}. The fracture surface has a transgranular nature with a brittle
appearance in the primary $\alpha$ phase. Long, straight and non-interacting
dislocations were observed in a cleavage-fractured primary $\alpha$ grain, with
basal and pyramidal traces. This is consistent with a dislocation emission view
of the the cracking mechanism.
