Stress Corrosion Cracking of Titanium Alloys

Abstract [en]

Stress and high temperature influence titanium alloys specially while they are in contact with other solid metals. This has led to an investigation how Ti-64, Ti-811 and Ti-6242 perform while in contact with copper and gold. A modified form of ASTM/SAE standard for stress corrosion cracking was established and used to test these titanium alloys. Parameters that could affect SCC were also understood like film thickness of copper and gold on the surface the samples.The solid metal contact was also evaluated to understand better the propagation of SCC in titanium alloys. The project was divided into two phases Batch 1 and Batch 2. The results from Batch 1 have been evaluated and compared to a previous study. Whereas in Batch 2 the modified form of ASTM/SAE standard testing was used. Ti-811 was used as the reference material for testing of SCC, the results from Ti-64 and Ti-6242 were evaluated in comparison with results obtained from Ti-811.
