Abstract:
The susceptibility to stress corrosion cracking in 3.5 percent sodium chloride solution of Ti-6Al-4V and Ti-6Al-6V-2Sn alloy plates in the annealed and solution treated and aged conditions was determined by tests of notched C- ring specimens with longitudinal, long transverse, and short transverse orientations. Test results indicated that the annealed material of both alloys was more susceptible to cracking in the long transverse direction than in the longitudinal and short transverse directions. In the solution treated and aged material of both alloys the short transverse direction showed slightly less susceptibility to cracking than did the longitudinal and long transverse directions, but the differences were not considered significant. Based on these results a recommendation was made that for plate of yield strength in all directions.
