Machines were built to diffusion bond by the yield strength controlled process and by a continuous seam process. Demonstration structures were fabricated and tested in titanium alloys, refractory metals, and dispersion strengthened materials. TD Nickel combustion cans were tested at 2000F, columbium alloy panels were tested at 2500F, tantalum alloy box columns were tested at 3000F, and a tantalum nosecap was tested to destruction up to 4000F. No mechanical failures of joints were found in any of these tests but sulfidation attack on TD Nickel was responsible for failure of bonds in this material. Continuous seam diffusion bonding was used to fabricate beams and panels in Ti-6Al-4V. Tensile, fatigue, end compression, and bending tests were performed without joint failures. Author
