TY  - JOUR
AB  - Hot salt stress corrosion cracking in Ti 6246 alloy has been investigated to elucidate the  chemical  mechanisms  that  occur.  Cracking  was  found  to  initiate  beneath salt particles  in  the  presence  of  oxidation.  The  observed  transgranular  fracture was suspected  to  be  due  to  hydrogen  charging;  XRD  and  high-resolution  transmission electron  microscopy  detected  the  presence  of  hydrides  that  were  precipitated  on cooling. SEM-EDS showed oxygen enrichment near salt particles, alongside chlorine and sodium. Aluminium and zirconium were also involved in the oxidation reactions. The role of intermediate corrosion products such as Na2TiO3, Al2O3, ZrO2, TiCl2 and TiH are discussed.
