Explosive Welding, Forming and Compaction


Book Description

The last two decades have seen a steady and impressive development, and eventual industrial acceptance, of the high energy-rate manufact turing techniques based on the utilisation of energy available in an explo sive charge. Not only has it become economically viable to fabricate complex shapes and integrally bonded composites-which otherwise might not have been obtainable easily, if at all-but also a source of reasonably cheap energy and uniquely simple techniques, that often dispense with heavy equipment, have been made available to the engineer and applied scientist. The consolidation of theoretical knowledge and practical experience which we have witnessed in this area of activity in the last few years, combined with the growing industrial interest in the explosive forming, welding and compacting processes, makes it possible and also opportune to present, at this stage, an in-depth review of the state of the art. This book is a compendium of monographic contributions, each one of which represents a particular theoretical or industrial facet of the explosive operations. The contributions come from a number of practising engineers and scientists who seek to establish the present state of knowledge in the areas of the formation and propagation of shock and stress waves in metals, their metallurgical effects, and the methods of experimental assessment of these phenomena.




Explosive Welding


Book Description

This reference explores explosion welding, a high intensity, transient impact that achieves metal compounds not obtainable otherwise. Electron microscopy images cover the structure of numerous welded joints including titanium–orthorhombic titanium aluminide, copper–tantalum, aluminum–tantalum, iron–silver, steel–steel, and copper–titanium. These weldable pairs have different solubility than their initial elements. The authors present various processes and structures including granulating fragmentation, cusps, splashes, and quasi-wave interface. Specific risk zones for chemical and petrochemical (coke chamber) reactors are probed and suggestions offered. Key Features: Offers new theories about explosion welding processes and structures Investigates dozens of weldable pairs with differing solubility from initial elements Studies both hetero- and homogeneous pairs Explores welded joints with flat, wavy and quasi-wavy separation boundaries Observes irregularities of the separation surface relief observing asperities and splashes and their transformation under intensified welding modes Unveils a new type of fragmentation under explosion welding Explosive Welding: Processes and Structures is a valuable resource for a wide range of experts involved in explosion welding, engineers, as well as graduate and postgraduate students.

Explosion, Shock-Wave and High-Strain-Rate Phenomena of Advanced Materials


Book Description

Materials processing using explosion, shock-wave and high-strain-rate phenomena was developed after WWII, and these explosive forming and welding techniques have since been adopted as an accepted industrial technology. Such extremely high-rate phenomena historically used empirical experiences while the experimental conditions were not well documented due to the difficulties inherent in understanding the real response or behaviour of materials. Based upon the recent development of numerical techniques for analysis and the enriched data available on the behaviour of materials, it is now possible to predict such high-rate phenomena based upon numerical and experimental approaches including optical observation. Explosion, Shock-wave and High-strain-rate Phenomena of Advanced Materials demonstrates the deformation of various materials at high-rate based upon numerical analysis and supported by experimental evidence. The book is recommended for researchers and engineers who would like to learn more about the high-rate effect of materials and those who need to resolve multi-physics problems based on numerical approach. It is also ideal for researchers and engineers interested with explosive and other high-rate processing of materials. - Presents numerical techniques on the analysis and enriched data on the behavior of materials based upon a numerical approach - Provides case studies to illustrate the various methods discussed - Includes mechanical response at high-rates of porous materials
