DIFFUSION BONDING OF TITANIUM ALLOYS.
Abstract
Using the alloy Ti-6Al-4V as a reference, the basic mechanisms in the solid state bonding of titanium alloys are being investigated. The following progress was made: Rod and plate stock of Ti-6Al-4V alloy was purchased and received; a supply of halogen-free cutting fluid was obtained. Initial use of this fluid indicates that it is effective in prolonging cutting tool life and reducing machining time; the vacuum hot press was modified to obtain more uniform temperature and bonding pressure; a series of specimens were bonded as part of an effort to better define the effects of time and surface finish on bond strength; a study was initiated to determine the effectiveness of ultrasonic scanning as a means of non-destructive testing of bonded joints; an examination of sample surfaces before and after cleaning was made using optical and electron microscopy. It was found that the cleaning process greatly changes the appearance of the surface. (Author)
