AgCl-induced hot salt stress corrosion cracking in a titanium alloy
Yitong Shi, Sudha Joseph, Edward A. Saunders +4
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 exam…
Fatigue cracking in gamma titanium aluminide
Claire F Trant, Trevor C Lindley, Nigel Martin +2
Cast and HIP'ed \textgamma-TiAl 4522XD is being developed for use in jet engine low pressure turbine blades, where temperature variations occur through the flight cycle. The effect…
The role of dwell hold on the dislocation mechanisms of fatigue in a near alpha titanium alloy
Sudha Joseph, Kavitha Joseph, Trevor C Lindley +1
The dislocation structures appearing in highly mis-oriented soft/hard grain pairs in near-alpha titanium alloy Ti6242Si were examined with and without the application of load holds…
Dislocation interactions and crack nucleation in a fatigued near-alpha titanium alloy
Sudha Joseph, Trevor C Lindley, David Dye
Dislocation interactions at the crack nucleation site were investigated in near-alpha titanium alloy Ti-6242Si subjected to low cycle fatigue. Cyclic plastic strain in the alloy re…
The mechanisms of hot salt stress corrosion cracking in titanium alloy Ti-6Al-2Sn-4Zr-6Mo
Sudha Joseph, Trevor C Lindley, David Dye +1
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…
