摘要： The process is described for bonding together of metal components wherein the components are explosively bonded together and the resulting composite is treated at elevated temperature. In the process the bond strength over weaker bonded areas is enhanced and the bond strength is rendered more uniform over the total bonded area. The process is especially advantageous for bonding high strength aluminum alloys such as aluminum/lithium alloys, and is particularly useful in the fabrication of composites bonded at selected areas for subsequent expansion to form hollow structures for use in aircraft components.

摘要： A method of explosively bonding metal plates into a multi-laminar composite plate wherein the metal plates are assembled over a restraining means, e.g. an anvil, in overlapping spaced-apart relationship, a driver plate having a mass of at least the total mass of the plates to be bonded is disposed over the top plate of the assembly at a stand-off distance of at least half its thickness, a buffer layer of granular inert material is disposed between the driver plate and the top plate, and an explosive layer is placed on the driver plate and detonated in the direction parallel to the driver plate. The number of plates which can be bonded in a single operation can be increased by placing an explosive layer driver plate and a layer of granular inert material symmetrically on each side of an assembly of metal plates and detonating each explosive charge simultaneously. The method produces multi-laminar composite plates having improved uniformity of bond quality at the interfaces. In addition the method allows increased areas of metal plate to be bonded without producing excessive wave amplitude at the interfaces.

摘要： In a method of explosively expanding a tubular metal component into engagement with a surrounding metal component, an explosive charge is disposed axially and fired in an insert having a hollow cylindrical container fitting closely within the portion of the tubular metal component to be expanded and having charge holding device, for example an axial pocket, to accommodate the explosive charge, the container being filled with a shock wave-transmitting liquid. Compared with solid inserts, the novel hollow insert is cheaper and requires a smaller explosive charge for a given operation. The method is especially advantageous for expanding large diameter tubes.

摘要： A metal tube is expanded by means of an explosive charge into engagement with a surrounding tubular metal member which is supported externally by a surrounding metal die member spaced from the metal member, the intervening space being filled with a shock transmitting liquid such as water. The metal die member is readily separated from the expanded tube and is reusable indefinitely without maintenance. Its use is therefore more economical than the split die hitherto used. The method is especially useful for expanding large diameter tubes, for example expanding oil-well drill pipes into pipe coupling members.

摘要： Clad metal plate comprising a layer of cladding metal bonded to a first substrate metal layer is produced by a method comprising initially metallurgically bonding a thin layer of substrate to a thick layer of cladding metal and bonding further layers of substrate metal to the first substrate layer in at least two roll bonding steps wherein the cladding layer is reduced to the desired thickness. The initial metallurgical bonding step may advantageously be a bonding method such as explosive bonding which is free from metal compatibility restrictions encountered in roll-bonding. The method enables a base metal such as carbon steel to be clad economically with a metal, for example titanium, with which it is incompatible for roll-bonding.

摘要： It is known to form a composite laminar metal structure, wherein two or more overlapping metal plates (11, 12, 21, 22, 23, 31, 32) are metallurgically bonded at their interfaces, impelling the plates (11, 12, 21, 22, 23, 31, 32) together by means of detonating an explosive charge (19), bonding of the plates (11, 12, 21, 22, 23, 31, 32) at selected areas (13) being prevented by covering the plates (11, 12, 21, 22, 23, 31, 32) at the selected ares (13) with a stopping-off material. The present invention improves this by providing metal sheet (14, 24, 34) which is placed in intimate contact with the stopping-off material, the metal sheet (14, 24, 34) being capable of metallurgically bonding to an adjacent metal plate (12, 21, 23, 32) at each selected area (13). The sheet (14, 24, 34) must be sufficiently thick to retain its' profile in the bonding process, and also sufficiently thin to leave an appropriate stand-off distance between itself and the opposing surface of the adjacent metal plate (12, 21, 23, 32) to ensure metallurgical bonding of the metal sheet (14, 24, 34) to the adjacent metal plate (12, 21, 23, 32).

摘要： An improved method is described for metallurgically bonding a composite metal plate (from which structural transition joints may be cut) wherein an outer layer and a metal interlayer of a different composition are propelled towards a metal base layer by means of the detonation of a layer of explosive disposed adjacent to the outer surface of the outer layer. The interlayer is only 0.25 to 4 mm thick and it is initially disposed at a stand-off distance from the base layer not exceeding 6 mm or 8 times the interlayer thickness. The outer layer has a mass of at least twice the mass of the interlayer and it is initially separated from the interlayer by a stand-off distance which is 0.5 to 10 times the thickness of the outer layer and is at least 3 times the distance between the base layer and the interlayer.

摘要： A method of forming a composite tube having an inner thin liner or layer of expensive material surrounded by a thick layer of less expensive material has been provided. A thin-walled tube of the expensive material is placed inside a thin-walled tube of a less expensive material and the outer tube is imploded by explosives to be metallurgically bonded to the inner tube. The composite billet thus formed is then placed within a third tube of any desired wall thickness which is of the same or similar material as the second tube. This composite is then co-extruded causing the like materials of the outer most tubes to be metallurgically bonded to each other. By this method, the relative ratios of the expensive and common materials can be selected as required by the particular use to be made of the billet and the diameters thereof can similarly be optimumly selected.

摘要： A tubejoint for a heat exchanger made of two dissimilar materials is provided wherein the tubeplate joint is manufactured by use of an explosive having a detonation velocity more than 120 percent of the sonic velocity of the tube materials to be welded. Very satisfactory welds are formed at subsonic velocity between the surfaces of concentric tubes made of dissimilar metal and along the surface of a counterbore formed in the hole in which the composite tube is placed. The joint thus formed prevents any corrosive fluid on the tube side of the joint from coming in contact with any non-compatible material on the shell side of the heat exchanger and also prevents any corrosive fluid on the shell side of the heat exchanger from coming in contact with incompatible material on the tube side of the heat exchanger. In the joint construction, a thimble made of the same material as the inner tube and as a clad layer on the tube side of the tubeplate is welded both to the tubeplate and to the inner tube to prevent any passage of fluid therethrough from the tube side to the shell side. A mechanical joint is formed on the shell side to prevent passage of fluid from the shell side through the aperture in the tubeplate to the tube side.
