Cladding with explosives

In cladding, an explosively driven metal plate (flyer plate) hits another plate (base plate) kept at a specified distance-greater than half the flyer plate thickness in order to allow this plate to achieve its maximum impact velocity. The extreme temperature and pressure produced with high-energy impact, bonds the plates together through a metallurgical bond. This technique is employed to bond... [Pg.48]

Plutonium-239 and tritium for use as military explosives are the two major transmutation products. The nuclear process for Pu-239 production is the same as for energy generation, but there are some differences (a) metallic natural uranium clad with aluminum facilitates later dissolution for plutonium recovery, and the reactor operates at a relatively low temperature because of the aluminum clad and better heat transfer (due to the metallic natural uranium) (b) the irradiation cycle is limited to a few months to minimize the Pu-239 conversion to Pu-240 and Pu-241 and (c) a carbon or a heavy water moderator is used to increase the neutron efficiency. [Pg.955]

Indirect Contact. Direct contact was more popular in the past, when none of the common construction metals was resistant to chlorine. Typical materials of construction were thermosets (such as a phenolic resin reinforced with asbestos) for vessels and stoneware or glass for piping. This situation changed with improvements in fiber-reinforced plastic fabrication and the commercial advent of titanium. The indirect-contact approach has now become a standard. The typical chlorine cooler today is a single-pass vertical shell-and-tube exchanger with titanium tubes and tube sheets and a carbon steel shell (or perhaps FRF in smaller units). Construction of tube sheets may be of solid titanium, or they may be clad or explosion-bonded with titanium. The inlet channel to the primary cooler also may be of titanium the other channels usually are of FRR... [Pg.785]

In commercial practice, powdered explosives on an ammonium nitrate basis are used in most cases. Typical detonation velocities are between 1800 and 3500 m/s depending on the metal system to be bonded. The lower detonation velocity range is preferred for many metal systems in order to minimize the quantity of solidified melt associated with the bond-zone waves (12). In addition, subsonic detonation velocity explosives are required for the parallel cladding technique in order to avoid attached shock waves in the coUision region, which preclude formation of a good bond. [Pg.148]

The clad plate is x-rayed perpendicular from the steel side and the film contacts the aluminum. Radiography reveals the wavy interface of explosion-welded, aluminum-clad steel as uniformly spaced, light and dark lines with a frequency of one to three lines per centimeter. The waves characterize a strong and ductile transition joint and represent the acceptable condition. The clad is interpreted to be nonbonded when the x-ray shows complete loss of the wavy interface (see X-ray technology). [Pg.148]

Chemical-Process Vessels. Explosion-bonded products are used in the manufacture of process equipment for the chemical, petrochemical, and petroleum industries where the corrosion resistance of an expensive metal is combined with the strength and economy of another metal. AppHcations include explosion cladding of titanium tubesheet to Monel, hot fabrication of an explosion clad to form an elbow for pipes in nuclear power plants, and explosion cladding titanium and steel for use in a vessel intended for terephthaHc acid manufacture. [Pg.150]

Some of the restrictions on the use of aluminum are caused by manufacturing and fabrication problems and by its low mechanical strength. However, aluminum is widely used and is competitive with Type 316 stainless steel in many instances. The explosion-bonding process has made the aluminum cladding of steel practical, and... [Pg.265]

X-Cord. Manufd by Explosive Technology, it is a metal-clad linear expl developed to sever materials, transmit an expl signal, or provide time delays in the microsecond range. Detonating velodties vary with the type of expl in the core... [Pg.392]

After the bomb had been filled, it, too, was ferried across to Gruinard. With it went Sutton, Henderson and Younger. Each man was now clad like some science fiction monster, in a rubberized suit, gas mask, high rubber boots and thick gloves. The anthrax weapon was placed on a small mound of earth. Around it, tethered in concentric circles, were the sheep. An explosive charge was carefully attached to the bomb and a fuse laid. While the sheep grazed unconcernedly, the scientists retreated to a safe distance down wind. [Pg.44]

Cladding joining of two metal plates, for example, explosive cladding of boiler plate HII with zirconium [Donat 1989]. [Pg.232]
