Effects of Electric Fields and Currents on Microstructure, Properties and Processing of Metals and Alloys

Abstract

This report presents a summary of the results obtained by the authors and coworkers at North Carolina State University (NCSU) during the past 10 years on the effects of electric fields and currents on the properties and processing of metals and alloys. These results confirm that an electric field or current can have a significant direct influence on the microstructure and properties of metals and alloys, in addition to the indirect effects of Joule heating or induced mechanical stresses. The resulting effects thus need to be taken into account when considering the use of metals and alloys (structural or electronic) in environments containing such field or currents. Moreover, the effects can be beneficial in the working, forming and processing of metals and alloys, offering opportunities regarding: (a) difficult-to-fabricate materials, (b) more efficient processes, (c) manipulation of microstructure and (d) improved properties of the product.
