Abstract: An improved method of explosively bonding a first metal to a second metal with an explosive composition comprising a base explosive in admixture with an inert particulate material, the improvement wherein the diluent comprises an inert material having a mean particle size selected from 0.05 mm to 0.1 mm, a hardness value of not less than 4 mohs, and a plurality of faces and edges. The explosive composition allows for a sustainable detonation value of less than 1800 m/s, preferably less than 1200 m/s to reduce or prevent the formation of interface waves.

Abstract: A method whereby a composite clad metal ingot can be produced for onward processing at higher temperatures which are sufficient to allow the properties of the substrate material to be adequately controlled to meet specific requirements. These higher temperatures are required to avoid the undue levels of work hardening which occurs at the lower temperatures previously employed because of the need to avoid the formation of deleterious intermetallics at the bonded clad substrate interface. Such intermetallics are formed at temperatures above approximately 850° C. and should they be present, will weaken or destroy the bond. The ingot, consisting of a steel or stainless steel substrate which is clad with a corrosion resistant metal, preferably of titanium, zirconium or their alloys, and containing an interlayer of high melting point metal of tantalum, niobium (columbium) or their alloys, is processed at temperatures above 900° C.
