| Abstract Scope |
Many bladesmiths have been interested in bonding titanium alloys to high carbon steel in a San Mai style for decades for aesthetic and performance reasons. However, getting a reliable bond proves quite challenging because of formation of brittle intermetallics at the steel/titanium interface. In this talk, two methods of bonding Ti6-4 to a simple high carbon steel utilizing vanadium as an interlayer are explored. Diffusion bonding in a high vacuum furnace and canned roll bonding were used as methods to achieve a 3 layer blade material with adequate mechanical properties to use in knives. Differences in these two bonding methods are looked at from the perspective of bond reliability, complexity of processing and practicality for bladesmiths.
