Abstract:

A diffusion bonding investigation of alpha-beta forded and alpha-beta rolled Ti-6Al-2Cb-1Ta-0.8Mo alloy titanium was undertaken as a first step in determining the feasibility of using out-of-chamber diffusion bonding for pressure hull fabrication. It was found that the mill processing history significantly affected the parameters necessary for bonding. The higher creep rate of the rolled material was primarily responsible for obtaining quality bonding at lower temperatures. It was also found that a total sample compression of more than 0.7 was necessary to obtain quality diffusion bonds. Modified author abstract
