<p>The disclosure teaches an improvement in an interlayer for bonding metallic articles. The articles are based on a metal chosen from the group consisting of nickel, cobalt, and iron, and the interlayer has a composition similar to that of the articles being joined, except for the addition of a quantity of at least one melting point depressant. The interlayer also has a brittle characteristic because of the formation of brittle phases. In accordance with the invention, the interlayer is provided in the form of a plurality of lamellae, each of the lamellae being free from those combinations of elements which form brittle phases. Thus, the lamellar interlayer is ductile even though its overall composition is one which would be brittle if produced in a homogeneous form. The invention also relates to a process for producing a ductile lamellar interlayer.</p> |
