Diffusion bonding between titanium base alloys and steels

摘要

Disclosed is a novel three-layered metallic interlayer material which provides good diffusion bonding between titanium alloys and steel or between titanium alloys and nickel alloys. The interlayer is comprised of three separate layers of metals as follows: a nickel layer which is placed in contact with the steel or nickel alloys, a Group V-B metal layer which is placed in contact with the titanium alloy and a copper layer which is sandwiched between the nickel and the Group V-B metal layers.
