Abstract
A method of joining titanium to a dissimilar metal wherein a predetermined amount of heat and pressure is applied sufficient to plastically deform only one of the metals being joined. The heat and pressure combine to flow one metal into shaped surfaces existing in the second metal, maintain the joint in compression through differrential thermal expansion and bonding the deformed metal to the other metal. The method uses a temperature sufficiently low to effect bonding without any chance for the formation of excessive brittle intermetallic phases.
