STUDY OF DIFFUSION BONDING OF TUNGSTEN ALLOYS
Abstract
A rocket motor test nozzle was designed to evaluate the techniques of diffusion bonding. Commercially pure W sheet and doped W sheet were given recrystallization heat treatments to determine the approximate recrystallization temperatures. Specimens 1-sq. in. were heattreated in 100 F increments from 2400 to 3100 F for 15 min. Each heat-treated specimen and an as-received sample of each material were metallographically prepared and photographed at 400X magnification. The recrystallization behavior of the materials for the given heat treatments are presented. Brazing tests with pure W sheet are being performed to evaluate the effects of braze joint thickness and joint coverage on the elevated temperature properties of the joints.
