Survey of Research into Electromagnetic and Other Wave Effects on MechanicalBehavior and Processing of Materials

摘要

In an effort to assess trends in the general areas of energy effects onmaterials, a survey was conducted for the period 1960-1990 of the open literature sources with special focus on electromagnetic and other wave phenomena. This survey has not treated nuclear, laser, or photoplastic effects. The statistics and trends in activity have been examined in four main areas: electric fields and currents, ultrasonics, microwaves, and magnetic fields. These energies have been found to affect the structure and mechanical properties of materials, and the changes, some of them substantial, are a main subject of this survey. In addition, beneficial effects, ranging from minor to significant, have been measured during the processing of materials with these energies. It is expected that future understanding and exploitation of these effects will be essential to the widespread development and use of future DoD systems such as electromagnetic guns, toward achieving economics of manufacturing through microwave processing of ceramic armor components and thick-section structural composites, and in other applications.
