Abstract : A new method of brazing in the 2000 to 3000 F temperature range referred to as the Con-Rad Process, was developed. Using this process, several 1 x 1, 6 x 6, and 12 in. x 12 in. brazed niobium alloy and diffusion bonded titanium sandwich panels were produced. Three of the brazed niobium alloy panels were cut into smaller test specimens. Room temperature and 2000 F edge compression tests indicated 100% braze joint efficiency. The elevated temperature use of such structure will be limited by the strength of the skin material, and not by the strength of the braze. (Author)
