Abstract

A series of 6Al-4V titanium pieces was diffusion bonded utilizing hot retort-cold press and vacuum hot press techniques. The time, temperature, and pressure parameters were varied with each specimen. The bonded specimens were a) examined metallographically in the bond area before destructive testing, b) ultrasonically before testing, c) monitored for acoustic emission during tensile pulling, and d) examined in detail using optical and electron fractography techniques, as well as metallography at the bondline, after failure.
