Explosive treatment of metals
Other work
Other applications making use of the energy of explosion include, for instance, explosive working of metals, sometimes also called explosive pressing. This technology is dominated by a procedure where the pressure generated by the detonation products of an explosion is transmitted via a water medium on to the surface of the part that is being worked, which is formed into a metal, concrete or polymer concrete mould. Its advantage is the possibility of working parts of spacious volume or components of complex shape using both common materials and materials difficult to melt by conventional methods.
Furthermore, the enumeration of applications of explosive detonations includes the explosive relief of residual stresses in the structures being welded, which is used mainly for spacious welded structures, usually of storage containers and tanks.
Historically, the explosive processing of materials also includes the explosive cutting of materials, although this procedure can be classified into destructive operations as well.
The utilisation of high pressures and temperatures has found its application in the explosive compaction (pressing) of powder metallic and non-metallic materials as well as in the synthesis of substances in environments with high pressures and temperatures. The phase transformation of inorganic crystalline materials makes use of the action of the shock wave produced by detonation, too.
In recent decades, considerable effort has been devoted to research and development in the processing of organic and biological materials through the action of shock waves and high pressures or the use of shock waves to separate materials.
The explosive surface treatment of materials usually does not use the energy of the explosives but the energy of the explosion of gas mixtures that accelerate the powder material and it is applied to the surface of the component at high speed and under increased temperature.
Transferring the energy of explosion to electrical energy is a marginal and not entirely industrial application.
