Abstract:

The basic mechanisms of solid state bonding of titanium alloys were being investigated using the alloy Ti-6Al-4V as a reference. Progress during the sixth quarter included the following 1 Shear tests and metallography where completed on six specimens bonded during the previous quarter. 2 A series of ultrasonic scan were made of the above six samples. The ultrasonic data was found to correlate well with the shear tests and metallographic examination. 3 Seven shear test samples were bonded under a variety of conditions to obtain additional information on the effects of finish and bonding time. 4 One 34 inch diameter by 3 inches long tensile specimen was bonded. The results of this experiment indicated a need to modify the bonding dies to eliminate radial constraint. 5 Shear test data from previous measurements has been fitted to a third order polynomial by means of a least squares program. 6 Data has been found in the literature on diffusion of fifteen elements in titanium including aluminum, vanadium, titanium, oxygen, nitrogen, and carbon.
