Diffusion bonding of a microduplex stainless steel to Ti-6Al-4V

In this study, a microduplex stainless steel (AVESTA 2205) and Ti-6Al-4V alloy were bonded for the first time. The bonding variables were chosen on the basis of the importance of grain boundary diffusion in alpha -phase of the titanium alloys. The study showed that the formation of Fe-Cr-Ti intermetallics is more important than sigma -phase formation during bonding. (C) 2001 Acta Materialia Inc. Published by Elsevier Science Ltd.
