Dynamic Materials Corporation is a metalworking business. The company operates in two segments, explosive metalworking and aerospace. The explosive metalworking segment utilizes explosives to perform metal cladding and shock synthesis. Its principal product is an explosion welded clad metal plate, which is used in the construction of heavy, corrosion-resistant pressure vessels, and heat exchangers for petrochemical, refining, and hydrometallurgy industries. The Aerospace segment provides welding services principally to the commercial and military aircraft engine markets, and to the power generation industry. Dynamic Materials Corporation was incorporated in Colorado in 1971. It was formerly known as Explosive Fabricators Inc. The company is headquartered in Boulder, Colorado. Wikipedia.

Zirconium is a commonly used material for containment of corrosive media by the chemical process industry (CPI). Zirconium's corrosion resistance is exceptional in a broad range of aggressively corrosive environments. However, zirconium is significantly more expensive than most of the alternative, but often inferior, corrosion resistant alloys. Explosion cladding has enabled CPI companies to cost effectively benefit from the superior performance features of zirconium in heavy-wall pressure vessels and heat exchangers. Explosion cladding is a unique technology that uses the energy of an explosive detonation to produce a metallurgical bond between metal plates. Since its discovery and industrialization in the 1960s, explosion cladding has proven to be a highly reliable, robust manufacturing technology. Zirconium clad has become a broadly accepted material of construction for a significant range of chemical process equipment. Zirconium clad equipment is used in manufacture of an extensive range of chemical products or intermediates including nitric acid, acetic acid, urea, and various organic acids. Zirconium clad and related design, manufacture, and fabrication processes have been shown to be highly reliable and to reduce both capital and operating cost. Copyright © 2010 by ASTM International.

Today's upstream oil and gas facilities frequently involve the combination of high pressures, high temperatures, and highly corrosive environments, requiring equipment that is thick wall, corrosion resistant, and cost effective. When significant concentrations of CO2 and/or H2S and/or chlorides are present, corrosion resistant alloys (CRA) can become the material of choice for separator equipment, piping, related components, and line pipe. They can provide reliable resistance to both corrosion and hydrogen embrittlement. For these applications, the more commonly used CRA's are 316L, 317L and duplex stainless steels, alloy 825 and alloy 625, dependent upon the application and the severity of the environment. Titanium is also an exceptional choice from the technical perspective, but is less commonly used except for heat exchangers. Explosion clad offers significant savings by providing a relatively thin corrosion resistant alloy on the surface metallurgically bonded to a thick, lower cost, steel substrate for the pressure containment. Developed and industrialized in the 1960's the explosion cladding technology can be used for cladding the more commonly used nickel based and stainless steel CRA's as well as titanium. It has many years of proven experience as a reliable and highly robust clad manufacturing process. The unique cold welding characteristics of explosion cladding reduce problems of alloy sensitization and dissimilar metal incompatibility. Explosion clad materials have been used extensively in both upstream and downstream oil, gas and petrochemical facilities for well over 40 years. The explosion clad equipment has demonstrated excellent resistance to corrosion, embrittlement and disbonding. Factors critical to insure reliable clad manufacture and equipment design and fabrication are addressed. © 2010 American Institute of Physics. Source

The ability to deploy a wide range of materials in a single comprehensive design gives engineers the freedom to be creative in solving weight related challenges. Dissimilar metal transition joints, made through the explosion welding process, are one of the material options all weight engineers should have in their 'toolbox'. Explosion welding has a long history of welding similar and dissimilar metals into one integrated material. Amongst the many uses of the product are structural transitions between highly dissimilar metals. Explosion welding can facilitate the design and fabrication of structures made from a wide range of metallic materials. It can also assist in improving current designs or preexisting joints made through other methods. The most common application may be the welding of aluminum to steel, but many other possible material combinations exist. This paper introduces the explosion welding process. It also covers some specific examples of dissimilar metal welding for light weighting and weight management in land, aerospace, and ocean based environments. Source

The microstructure of explosive cladding joints formed among parallel Ti and steel plates was examined by electron microscopy. The bonding interface and the bulk materials around it form pronounced hierarchical microstructures. This hierarchy is characterized by the following features: at the mesoscopic scale of the hierarchy a wavy course of the interface characterizes the interface zone. This microstructure level is formed by heavy plastic shear waves (wavelength≈0.5mm) which expand within the two metal plates during the explosion parallel to the bonding interface. At the micro-scale range, intermetallic inclusions (size≈100-200μm) are formed just behind the wave crests on the steel side as a result of partial melting. Electron diffraction revealed FeTi and metastable Fe9.64Ti0.36. Most of the observed phases do not appear in the equilibrium Fe-Ti phase diagram. These intermetallic inclusions are often accompanied by micro-cracks of similar dimension. At the smallest hierarchy level we observe a reaction layer of about 100-300nm thickness consisting of nano-sized grains formed along the entire bonding interface. Within that complex hierarchical micro- and nanostructure, the mesoscopic regime, more precisely the type and brittleness of the intermetallic zones, seems to play the dominant role for the mechanical behavior of the entire compound. © 2010 Elsevier B.V.
