Cylindrical tensile specimens prepared from wrought Ti64 and IMI834 alloys were investigated for HSSCC susceptibility of Ti alloys. These samples were salt coated using dip coating method in 25% NaCl solution in a hot salt bath and then dried completely to remove all the moisture content in salt coating.These samples were subjected to slow strain rate testing (SSRT) at a strain rate 10^-6mm/s at different elevated temperatures. Samples failed due to SCC and were characterized for analysis of type of failure using optical microscopy and SEM.A critical comparison was made between two alloys w.r.t.their mechanical and microstructural properties in order to study nature and mode of cracking failure for both alloys.Possible causes and mechanisms of cracking failure was studied and proposed.Investigations showed cracking susceptibility and severity of failure for both alloys increases with increasing temperature.It was concluded that the hot salt stress corrosion cracking process is accelerated at elevated temperatures.
